Schematic of the CW dual-wavelength Alexandrite laser. Tentatively, a high crystal quality is more difficult to achieve in combination with a high Cr3+ doping concentration. Alexandrite laser is a 755 nm wavelength. [4] However, in a review of 21 case reports, 33% of cases had severe ocular injury even when proper use of wavelength-specific goggles and intraocular corneal shields were used. The Apogee Elite combines a 755nm Alexandrite laser and a high-powered 1064nm Nd:YAG laser. The GentleMax Pro laser is a true work horse in my practice. Delivering laser pulses faster allows for quicker and more convenient treatment times, benefitting both patients and providers. 52% of the population is considering hair removal with an aesthetic device2, Average of 3 sessions for pigmented lesion treatments, Hair removal is one of the top 3 non-surgical aesthetic procedures3. The energy of the laser light is defined by the number of photons delivered to the target and is measured in joules (J). %PDF-1.5
The patient must wear eye protection consisting of an opaque covering or goggles throughout the treatment session. [4], Signs of ocular injury due to cosmetic laser procedures are typically easy to identify due to the short temporal relationship between laser exposure and symptom onset. Lasers are especially dangerous when the light is not in the visible spectrum, since it is unclear when the device is on. 755nm alexandrite has dermatological uses. An alexandrite laser is one that uses an alexandrite crystal is used as the laser source or medium. It can also be used for narrowband lasing on the R-line. Without enough energy in each pulse, there is no pigment fragmentation and no tattoo removal. [9][14] More severe injuries are associated with longer exposure durations, shorter exposure distances, and higher fluences. [2] Since laser radiation can reflect from shiny surfaces, it is imperative that the provider also wear protective goggles. Asiri MS, Alharbi M, Alkadi T, Abouammoh M, Al-Amry M, Al Zahrani Y, et al. Alexandrite rods are usually 0.3 to 0.7 cm in diameter and 7.6 to 10 cm long. %
Alexandrite is the leader of a class of tunable solid-state laser materials. In the case of hair removal, the light from a long-pulse laser is preferentially absorbed in the hair shafts, and the resulting heat damages these hair shafts and the surrounding hair follicles (selective photothermolysis). The ideal wavelength would be a laser between 750 and 950 nm. [4][15], Having a pupil size of 2-3mm and having a history of ocular abnormalities are associated with an increased risk of ocular injury from cosmetic lasers. Laser treatment of periocular skin conditions. Methods to overcome poor responses and challenges of laser hair removal in dark skin. Green and black inks are especially easy to remove, since the base laser color ranges from red to yellow. It continues to be my go-to laser for hair removal, no matter how many hair removal lasers I try. Each of the different types of lasers has a specific range of utility, depending on its wavelength and penetration. By cooling the skin during the treatment, damage to the epidermis is minimized. The laser is converted to heat energy in order to dissolve the unwanted skin cells or hair follicle. The colour of the tattoo and the depth of the pigment influence the duration and the outcome of the laser treatment for tattoo removal. Note: the article keyword search field and some other of the site's functionality would require Javascript, which however is turned off in your browser.

Users must understand the importance of wearing proper eye protection, avoiding direct gaze, and avoiding use of the laser in a room with highly reflective surfaces such as mirrors.[27]. Some common complications include erythema in the treated region, scarring, bacterial infection, and hyper- or hypopigmentation.[10]. It is also suitable for men's arms. endobj
It has a wavelength of 755 nm which is . This together with the strong birefringence of the material makes it easy to obtain linearly polarized emission with low depolarization losses. (If you later retract your consent, we will delete those inputs.) Yates B, Que SK, D'Souza L, Suchecki J, Finch JJ. With use of the DCD, we can carefully protect the patients epidermis from harm, while also keeping the patient comfortable during treatment. We report the first ever demonstration of a wavelength-locked Alexandrite laser using a volume Bragg grating (VBG) as a wavelength-selective mirror. An Alexandrite Laser is a type of LASER (light amplification by stimulated emission of radiation) that emits high energy light through an alexandrite crystal. Bruising affects up to 10% of patients. [26] While this may not be necessary in cosmetic laser procedures, cooling of periorbital regions can help protect against epidermal injury. One of the most important aspects of the GentleMax Pro system that makes it so attractive to me as a physician looking to deliver optimal results, while also keeping the patients free from harm, is the Dynamic Cooling DeviceTM (DCDTM). GentleLase Pro by Candela: A 755 nm Alexandrite laser optimal for skin types I-III. In some ophthalmologic laser procedures, corneal cooling via eye irrigation with a chilled balanced saline solution is performed and has been found to be effective in preventing ocular injury. However, the use of a laser instead of one or two lamps for pumping greatly increases the cost of the device. Amin SP, Goldberg DJ. In a study of 40 patients with ocular injury, only 15% were wearing protective eyewear. It has two wave lengths, the 755 nm Alexandrite and the 1064 nm Nd:YAG. An alexandrite laser is one that uses an alexandrite crystal is used as the laser source or medium. This is an award winning workstation in lasers. Alexandrite Laser technology uses the selective photothermolysis approach, meaning that a timed pulse of an energy-filled laser beam channels through the surface of the skin to the the targeted treatment area. The Alexandrite technique is a common form of laser hair removal. Any laser or light source with wavelengths of about 600 to 1100 nm is absorbed by melanin and well suited for hair removal.

Juhasz M, Zachary C, Cohen JL. Lett. . The laser's wavelength, fluence, pulse duration and spot size determine the effectiveness of the treatment and also influence the depth of penetration and treatment speed. The wavelength of high energy light emitted by the laser is converted to heat energy and this damages the specific target area. [4], Topical or oral ascorbic acid is often prescribed to promote fibroblast activity to minimize ocular damage. The number of sessions depends on the area of the body being treated, skin colour, coarseness of hair, underlying conditions such as polycystic ovaries, and. The short pulse duration obtained with a Q-switched laser favors the preferential heating of small ink particles. If youre going to be offering any service, particularly laser hair removal, you have to choose the best, and the GentleMax Pro system is the number one laser hair removal device on the market. Am. The light energy delivers a pulse of light that breaks up the darker colored cells. Redness, swelling and itching immediately after the procedure that may last a few days after treatment. Lack of adherence to safety precautions and accidental misdirecting of lasers can cause ocular injury during periorbital laser treatments. Alexandrite lasers can be pulsed or continuous, depending on the requirements of the operation. The longer wavelengths avoid skin damage superficially near the skin's surface in darker skin patients. With preview image (see the box just above): For Wikipedia, e.g. [4] Safety precautions must be followed to protect both the provider and patient throughout the laser procedure. Dermatology Made Easybook. 2023 The Laser Warehouse, LLC. Many patients describe each pulse to feel like the snapping of a rubber band against the skin. Alexandrite lasers are also available in the Q-switched mode.

The Alexandrite laser penetrates the skin 755nm (nanometers) deep and is suitable for skin types 1 through 4 and not recommended for darker skin types 5 and 6. The fundamental emission wavelength of this laser is 752 nm. Note: this box searches only for keywords in the titles of encyclopedia articles. The high pulse energy and average power allow for a reasonably short treatment time. Sufficient energy must be delivered during each laser pulse to heat the pigment to fragmentation. 1J or even several joules can be readily obtained with relatively simple laser resonators, which, however, deliver a relatively poor beam quality M2 factors of the order of 10 or larger are typically obtained. [10] It is critical that all cosmetic laser providers have sufficient medical knowledge to counsel patients on postoperative complications, and should be able to recognize the common signs of ocular damage. For example, one patient developed bilateral bullous keratopathy following CO2 laser facial resurfacing, most likely due to overheating of the metal shields from inadequate cooling time between laser pulses. Ive had the GentleMax Pro laser system now for about ten years and we use it for a full range of skin types and hair types. With a long-term efficacy of 65%-80.6%, it is effective at hair removal and is commonly used on people with lighter skin tones (Fitzpatrick Types I-III). If you need to face many different clients when doing permanent hair reduction treatment, take a look at this cutting-edge machine. While cases of ocular injury due to cosmetic lasers remain rare, they can be minimized by adhering to proper safety protocols before, during, and after the procedure. The church is of major importance in . One case report described a dermatologist who experienced central scotoma after performing a procedure using a Nd:YAG laser without wearing protective eyewear. But hair removal is not the only application of this advanced technology. Various kinds of lasers are available for use in skin surgery. An analysis is made of laser efficiency and mode formation including the creation of higher-order Laguerre-Gaussian vortex modes (LG 01 and LG 02). This provides the best solution for the widest range of hair types and colours, especially thin and light hair. Treatments are quick, non-surgical and provide great results. In a review of 21 case reports of ocular injuries due to cosmetic lasers, 62% involved no protective eyewear or the removal of goggles when treating periorbital regions. For active Q switching, one would typically use an electro-optic modulator. They can cause tissue to generate enough heat to denature proteins. Alexandrite was one of the first few vibronic laser gain media, discovered in the late 1970s. [1] It emits wavelengths in the visible and infrared light spectrum. Share this with your friends and colleagues, e.g. DermNet provides Google Translate, a free machine translation service. Alexandrite laser for the treatment of port wine stains refractory to pulsed dye laser. The medium amplifies the light of a particular wavelength as it passes through it. The author will decide on acceptance based on certain criteria. Due to the large beam area, there are no special requirements on beam quality. Lett. Ocular injuries secondary to alexandrite laser-assisted hair removal. There are currently no guidelines on dosing and preferred medications for ophthalmologists specifically for cosmetic laser-induced ocular injury. Alexandrite can be used to make wavelength-tunable lasers with emission ranges between 710 and 800nm. 21 (15), 1150 (1996). Essentially, the issue must be of sufficiently broad interest. The tunable emission was observed at room temperature and above in a homogeneously broadened, vibronic, four-level mode of laser action.

The long-pulse Alexandrite Laser has the ability of deep penetration into the dermis. Alexandrite (Cr3+:BeAl2O4, chromium-doped beryllium aluminate) is a 4-stage energy laser material used in an adjustable wavelength of 700-820nm. This website contains registered and unregistered trademarks, trade-names, service marks and brand names of Candela Corporation and its affiliates. An analysis is made of laser efficiency and mode formation including the creation of higher-order Laguerre-Gaussian vortex modes (LG 01 and LG 02 ). The short pulse duration of 50 to 100 nanoseconds allows laser energy to be confined to the tattoo particle (approximately 0.1 micrometres) more effectively than a longer-pulsed laser. Often laser hair removal brings patients into my practice; but the way you keep them in your practice, is number one, you provide a great service, so that means you deliver long lasting hair reductions. The short emission wavelength of an alexandrite laser, compared with that of a Nd:YAG laser, is beneficial for removing finer hairs, but increases the risk of skin damage in the case of darker skin. Diode lasers also perform slightly better on coarse hair like pubic hair. Non-Ocular Side Effects of Cosmetic Lasers. We have men who come in for treating hair on their backs and shoulders, and then realize they can benefit from other treatments such as brown spots and rosacea, really broadening treatment opportunities. Near the optimal wavelength of 750 nm, you can achieve maximum laser gain and electrical-to-optical power efficiency. Excellent pump . It is considered a red light laser. Sorry, we don't have an article for that keyword! [8] KTP and PDL lasers are commonly used to treat facial redness and reduce acne scars. Intravitreal bevacizumab 1.25mg/0.05mL was found to be highly effective in these cases, restoring vision back to 20/20 with complete involution of the membrane. A common laser combination is 1064 nm (Nd:YAG), 532 nm (frequency doubled Nd:YAG) and 755nm (alexandrite). Short 2 ms pulse durations offer new, finer hair treatment capabilities. It is a dual wavelength laser platform that combines the fastest and most powerful 755 nm Alexandrite laser with the 1064 nm Nd:YAG laser for high performance treatment capabilities in . He may bring in new perspectives and ideas. He has a good overview on many technologies and their potentials and limitations. However, in this application area alexandrite lasers are not often used, partly because titaniumsapphire lasers offer much broader tunability in that wavelength region and also exhibit much larger transition cross-sections, which can be advantageous in various respects. Diode lasers use a longer wavelength (usually around 810nm). Alexandrite has an orthorhombic crystal structure, having a low symmetry. This results in the release of a photon of light as it returns to a stable state. With the GentleMax Pro system, you have two lasers, and just from that starting point, you can treat a whole, wide array of skin conditions, and a really broad range of skin types. The precision and ability to pass through the skin layers to get straight to the ink enables the correction to leave little to no damage to the surrounding skin tissue. One study found that plastic shields melted or caught fire when radiation from long-wavelength Nd:YAG and carbon dioxide lasers were applied. With 755 nm and 1064 nm dual wavelengths for laser hair removal, vascular and skin treatments, as well as multiple spot sizes and variable pulse duration, the Gentle Pro Series is a foundational device for all practices. Thats why the GentleMax Pro laser is so important because I get happy, satisfied patients that ultimately move on to other procedures which grows my aesthetic business. Higher fluences, larger spot sizes and shorter pulse durations all point to the power of the new GentleMax Pro Plus platform. We specialize in alexandrite, Nd:YAG, Er:YAG and CTH:YAG gain media. Until the mid-19th century, when industries developed there, it was only a small township centred on its famous abbey church, which had been the burial place of the kings of France. (Please enter the sum of thirteen and three in the form of digits!). 6.3mm (1/4 inch) are used and lamp-pumped with one or two xenon flash lamps. Whether its being utilized by myself, my partner or my physician assistant, we use the GentleMax Pro device for laser hair reduction, plus for treatment of pigmented lesions and vascular lesions. The following skin disorders can be treated with Alexandrite laser beams. Wavelength tuning and dual wavelength operation is produced using the self-birefringent filtering of the Brewster-cut Alexandrite crystal. endobj

If you wish to receive personal feedback or consultancy from the author, please contact him, e.g. Providers often ask patients to remove their protective eyewear when targeting periorbital regions, such as during eyebrow epilation, to have easier access to the target area. The alexandrite laser was originally designed to be a fixed wavelength laser, but later was developed into a tuneable solid-state laser. Figure 4. are found in the RP Photonics Buyer's Guide. <>/XObject<>/ProcSet[/PDF/Text/ImageB/ImageC/ImageI] >>/MediaBox[ 0 0 612 792] /Contents 4 0 R/Group<>/Tabs/S/StructParents 0>>
As a consequence of that, the absorption and gain properties strongly depend on the direction of polarization of light. The treatment time depends on the form, size and location of the lesions as well as the skin type. In this paper we investigate the performance of an Alexandrite laser pumped by a high-power fiber-delivered blue diode module. [4][11], In patients with light-colored eyes, the laser is more likely to penetrate past the iris and cause damage in the posterior eye structures. Using our ad package, you can display your logo and further below your product description. Alexandrite laser is a solid state laser in which Chromium ions (Cr +3 ), at the amount of 0.01-0.4 %, are embedded in BeAl 2 O 4 crystal . The substantial wavelength tunability, which is made possible by the wide emission spectrum of alexandrite, can be exploited in laser spectroscopy. I would recommend the GentleMax Pro laser system to my colleagues for lots of reasons, but primarily because its so reliable and powerful. It is important that the correct diagnosis has been made by the clinician prior to treatment, particularly when pigmented lesions are targeted, to avoid mistreatment of skin cancers such as melanoma. For continuous-wave lasers, however, the reduced upper-state lifetime at elevated temperatures can degrade the performance. The DCD is perfectly synchronized with each laser pulse, to cool the epidermis, allowing the laser energy to reach the deeper targets within the skin that are, in fact, what were trying to eradicate. Soc. Periocular CO. Balyen L. Inadvertent macular burns and consecutive psychological depression secondary to Alexandrite laser epilation: A case report. This means that relatively simple lasers can be used for such purposes. Huang A, Phillips A, Adar T, Hui A. Ocular Injury in Cosmetic Laser Treatments of the Face. An entire back can be treated for hair removal in only 30 minutes. van Gemert MJC, Bloemen PR, Wang WY, et al. The GentleMax Pro is a single consolidated system that delivers a range of treatments - all skin type hair removal, as well as pigmented and vascular lesions. [29] This suggests that mid-level providers or aestheticians comprise a large proportion of cosmetic laser operators. Patients with darker eyes will more often report pupillary abnormalities such as iris atrophy, since the melanin in the iris absorbs most of the radiation. This settles by itself. Procedures can be performed by licensed physicians, mid-level practitioners, and aestheticians, generally with self-limited side effects such as mild pain, redness, and edema. As the light passes through the alexandrite crystal, a beam of light 755 nm long is produced. An unusual phenomenon is that the achievable laser gain and efficiency are highest not at low temperatures, but at elevated temperatures of e.g. several tens of kilohertz or mode-locked operation. I personally would recommend the GentleMax Pro laser to anyone whos looking to really start to build their practice for the first time with an energy-based device. In comparison to ruby lasers, the high pulse repetition rates and average power of alexandrite lasers is beneficial for such applications. The carbon dioxide laser (10,600 nm) is the highest-power laser that is currently available. [1] Lasers with higher wavelengths (such as diode and Nd:YAG) which are more likely to cause ocular damage, are better suited for effective hair and pigment removal from people with darker skin. especially high. We report on a continuous-wave alexandrite (Cr3+:BeAl2O4) microchip lasers operating at 680.4 nm and 749.5 nm laser wavelengths. GentleLase Laser. 416 South Military Trail Deerfield Beach, FL 33442 Tel: 954-254-4612. Although large alexandrite crystals can be fabricated with high optical quality, the effective optical damage threshold for large beam area can be far below the intrinsic damage threshold as can be measured on high-quality spots which are selected for particularly low scattering losses. The availability of high-power and high-brightness blue diode lasers makes them attractive as low-cost pump sources for broadly tunable Alexandrite lasers. Due to the particularly high mechanical and thermo-mechanical strength of the material and its benign thermo-optical properties, very high pump powers can be applied to the flash lamps (often with average powers of several kilowatts) substantially more than in lamp-pumped Nd:YAG lasers, for example. It allows for the greatest absorbency of the melanin chromophore. The alexandrite laser was originally designed to be a fixed wavelength laser but later was developed into a tuneable solid-state laser. Furthermore, Bells phenomenon (where the eye naturally rolls upward upon eyelid closure) increases the risk of damage to the iris by bringing anterior eye structures closer to the lasers radiation range.
