During the course of treatment, patients should protect the area from sun exposure to reduce the risk of, Pain during treatment (reduced by contact cooling and if necessary, topical anaesthetic). The alexandrite laser, which is almost in the middle of this spectrum with its 755-nm wavelength, represents an ideal choice. It is the U.S. FDA-approved machine with a long pulse width, leading to increased treatment speed and providing convenience to the patient. Nonetheless, data on the long-term efficacy of the 755-nm alexandrite picosecond laser are limited. Alexandrite was one of the first few vibronic laser gain media, discovered in the late 1970s. Wavelength tuning and dual wavelength operation is produced using the self-birefringent filtering of the Brewster-cut Alexandrite crystal. People [ edit] Saint Denis of Paris, 3rd-century Christian martyr and saint, patron saint of Paris. Frdric St-Denis (born 1986), Canadian hockey player. This together with the strong birefringence of the material makes it easy to obtain linearly polarized emission with low depolarization losses. Corneal shields are especially important for the patient to wear when protective goggles are unfeasible, such as during eyeliner tattoo removal or eyelash cauterization. They can cause tissue to generate enough heat to denature proteins. Alexandrite is a common name for chrysoberyl (BeAl 2 O 4) doped chromium (Cr 3+) ions and is used as the active medium in this laser. By cooling the skin during the treatment, damage to the epidermis is minimized. Vascular lesions may require multiple treatments. Tattoos can be removed or at least lightened by applying light which can be absorbed by the used ink, which is then chemically transformed and subsequently removed by the body. Definition: solid-state lasers based on alexandrite (Cr3+:BeAl2O4) crystals, Category: laser devices and laser physics, How to cite the article; suggest additional literature, URL: https://www.rp-photonics.com/alexandrite_lasers.html.

A carefully designed and complex ring resonator with several functional components is combined with an innovative pumping scheme with high-power red laser diodes. J Cosmet Laser Ther. The spectroscopic properties of alexandrite are substantially more complicated than those of Nd:YAG, for example not only due to the directional dependence, but also because of the strong involvement of phonons (quantized lattice vibrations) in the lower laser level. We can provide a wide array of standard sized pump cavities, and can assist in the design of custom cavities for specialized applications. [4] The wavelength must penetrate deep enough to affect the target. [7], The neodymium-doped yttrium aluminum garnet (Nd:YAG) laser is a long-wavelength laser that is considered to be the best for hair removal on darker skin (Fitzpatrick Types IV-VI). 2006 Jun;8(2):65-8. . Alexandrite was one of the first few vibronic laser gain media, discovered in the late 1970s. Saint-Denis, city, a northern suburb of Paris, Seine-Saint-Denis dpartement, le-de-France rgion, north-central France. 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. This results in the release of a photon of light as it returns to a stable state. Arsiwala SZ, Majid IM. It is an Alexandrite laser, which means it uses alexandrite crystal as its source. However, obtaining a thorough history and physical exam can help ophthalmologists determine the appropriate treatment regimen for the patient. [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. Alexandrite rods are usually 0.3 to 0.7 cm in diameter and 7.6 to 10 cm long. All rights reserved. Steroids and cycloplegics have been found to be beneficial in restoring vision.

This work presents a study of a fully nonastigmatic design of a single-longitudinal-mode, wavelength-tunable, unidirectional alexandrite ring laser cavity and assessment of its performance compared to more complex laser design requiring astigmatism compensation. 3 0 obj 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. The energy transferring do not require touch skin. The alexandrite laser uses a wavelength of 755 nm. M1 is a highly reflecting flat mirror. Alexandrite is the leader of a class of tunable solid-state laser materials. Alexandrite lasers are chromium-doped solid-state lasers based on the crystalline gain medium alexandrite, which is Cr3+:BeAl2O4. 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 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 . Alexandrite lasers cause very precise tissue destruction of the lesion and leave the tissue in the surrounding area undamaged. 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. Pulse energies of e.g. Depression has been reported in cases with reduced vision after cosmetic laser procedures. By continuing to browse you are agreeing to our use of cookies, Photos courtesy of: O. Zerpa, MD, Venezuela, Photos courtesy of: Candela Institute for Excellence. [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. It continues to be my go-to laser for hair removal, no matter how many hair removal lasers I try. ND yag laser like alexandrite laser wavelength is 755nm and 1064nm. 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. 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. Periocular CO. Balyen L. Inadvertent macular burns and consecutive psychological depression secondary to Alexandrite laser epilation: A case report. Although not technically a laser since it uses a broad spectrum approach, intense pulsed light (IPL) is a lower cost light treatment method or hair removal that is commonly used for larger skin areas, such as the back, chest, or legs. Lin CC, Tseng PC, Chen CC, Woung LC, Liou SW. Iritis and pupillary distortion after periorbital cosmetic alexandrite laser. 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.

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 ). Depending on the area, the skin will remain completely clean and smooth for around 6 to 8 weeks after treatment; it is time for the next session when fine hairs start to grow again. It can also be used for narrowband lasing on the R-line. J Clin Aesthet Dermatol. The Gentlemax has both the 1,064 Nd:YAG and 755 Alexandrite wavelength lasers in one machine. The fundamental emission wavelength of this laser is 752 nm. 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]. We report the first ever demonstration of a wavelength-locked Alexandrite laser using a volume Bragg grating (VBG) as a wavelength-selective mirror. 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. [6], The alexandrite laser is considered to be a long-wavelength laser, despite having one of the shorter wavelengths in the category. There are a few alternative wavelengths to the 755 nm, such as 785 nm (Ti:Sapphire) and 694 nm (Ruby). This laser is recommended for persons with light skin tones since it is believed to hurt somewhat less than other lasers. Specifications: Wavelength: 755 Pulse width: 2-20 Fluence: 10-40 Spot size: 5-10 Repetition rate: 1-5, Devices available: Three different alexandrite lasers are available:Apogee-40 (Cynosure), EpiTouch Alex (formerly ESC Sharplan, now Lumenis.) The tunable emission was observed at room temperature and above in a homogeneously broadened, vibronic, four-level mode of laser action. [18], While there are numerous case reports describing the initial symptoms and clinical findings of patients with ocular injury following a cosmetic laser procedure, there is little consensus on the long-term sequelae and outcomes of these patients. The Alexandrite technique is a common form of laser hair removal. For particularly high output average powers, a zigzag slab laser design may be used, where thermally introduced beam distortions are reduced. A CTO of a laser company needs to know whether some new technical idea is worthwhile pursuing. GentleLASE (Candela) Disadvantages: Hair removal is short term. Small red vessels can usually be removed in only 1 to 3 sessions and are generally invisible directly after the treatment. In one study of 40 patients with ocular injury, 34 did not wear protective eyewear, and 5 wore goggles that were not wavelength-specific. The photon quantum efficiency (ratio of laser to pump photon energy) = p / L = 84% where p and L are the pump and laser wavelength, respectively. Juhasz M, Zachary C, Cohen JL. Anderson RR, Parrish JA. The alexandrite laser was originally designed to be a fixed wavelength laser but later was developed into a tuneable solid-state laser. Treatment consists of placing a handpiece against the surface of the skin and activating the laser. Applications /|ff|@dzvk%^x~/d|]mGb& yh,[]m1;tSs&z>Dso bR>f . The GentleMax Pro device is a very versatile laser system for hair removal and more. Encyclopedia > letter A > alexandrite lasers. The majority of cases of ocular damage due to cosmetic exposure have occurred when safety precautions were evaded. A misdirected laser beam towards the eye or any reflective surface can penetrate the eye even when the lids are closed. Kataoka T, Zako M, Takeyama M, et al. Selective photothermolysis: precise microsurgery by selective absorption of pulsed radiation. An unusual phenomenon is that the achievable laser gain and efficiency are highest not at low temperatures, but at elevated temperatures of e.g. It is also possible to use cavity dumping in order to achieve even shorter pulse durations of e.g. %PDF-1.5 The Alexandrite laser produces a specific wavelength of light and is considered a red light laser. [8] It is effective at removing layers of skin and is used for facial resurfacing, minimizing wrinkles, and removing scars. Gan SD, Graber EM. The applicable peak intensities or fluence is in pulsed lasers or amplifiers are strongly dependent on the crystal quality. Semin Cutan Med Surg. Cynosure is a leading company in lasers. [22], Choroidal neovascularization can occur as an adverse event. [1] The longer wavelength allows for less melanin absorption by the epidermis, with higher specificity of absorption by hair follicles. Any laser or light source with wavelengths of about 600 to 1100 nm is absorbed by melanin and well suited for hair removal. (One sometimes uses particularly powerful xenon lamps which would be able to fracture a Nd:YAG rod.) 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. He has a good overview on many technologies and their potentials and limitations.

The lasers are able to substantially lighten and/or remove tattoo ink with a low risk of scarring, particularly for light-skinned patients. It is also suitable for men's arms. 6.3mm (1/4 inch) are used and lamp-pumped with one or two xenon flash lamps. The light energy delivers a pulse of light that breaks up the darker colored cells. Then it repeats, starting at 9. Treatments are quick, non-surgical and provide great results. Carbon dioxide is followed by alexandrite, diode, and Nd:YAG in most common lasers implicated in ocular injury. Look at the difference a few treatments can make. Essentially, the issue must be of sufficiently broad interest. Other drugs that may be considered are topical prostaglandin analogs, topical antibiotics, injectable anti-vascular endothelial growth factor drugs, and appropriate surgical intervention.[10]. 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. Each of the different types of lasers has a specific range of utility, depending on its wavelength and penetration. [21][24] It is important for providers to wear wave-specific goggles while operating on patients wearing metal corneal shields, since laser radiation can reflect off the surface. This provides the best solution for the widest range of hair types and colours, especially thin and light hair. The wavelength of the Alex laser is 755 nm. We call that applying. There are couple of companies that make lasers with this wavelength. [2] It can be concluded from these cases that diode laser can be cataractogenic. Alexandrite can be used to make wavelength-tunable lasers with emission ranges between 710 and 800nm. 2, Table 6.1 ). It has energy level structure similar to the energy level structure of Ruby laser. Note: this box searches only for keywords in the titles of encyclopedia articles. The medium amplifies the light of a particular wavelength as it passes through it. Tattoos that have not been effectively removed by other treatments may respond well to laser therapy, providing prior treatment has not caused excessive scarring or skin damage. Denis the Carthusian (1402-1471) Brent St. Denis (born 1950), Canadian politician. We are a leading provider of used cosmetic lasers, used medical lasers and other aesthetic equipment.

[16], Complications have also been reported due to incidental laser exposure with use of metal corneal shields. Enjoy a compact introduction to laser technology: This book soon became a bestseller among the SPIE Field Guides. [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. It is fast and very effective with lighter skin and dark, fine hair. https://eyewiki.org/w/index.php?title=Ocular_Injuries_Due_to_Cosmetic_Laser&oldid=88987, Visual abnormality (includes decreased visual acuity, blurriness, shadow, scotoma, and metamorphopsia), Corneal abnormality (includes swelling, abrasion, ulceration, and epithelial defects), Pupillary irregularity (includes iris atrophy), Increased intraocular pressure or glaucoma. [22] Macular SD-OCT would reveal hyper-reflective lesions. Laser therapy is one of the effective treatments for PIH, and various wavelength lasers and light devices have been utilized in PIH therapy. Spinel and alexandrite are both capable of producing photoluminescence with a long lifetime: spinel between 9 and 23 microseconds and alexandrite from 25 to 53 microseconds. The outcome of laser treatment depends on multiple factors, including the parameters of the laser used (fluence, wavelength, pulse duration) and the patient profile (skin type and hair color). 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).
