TECHSPEC Nd:YAG Laser Output Couplers are manufactured from UV fused silica substrates to provide excellent thermal properties and feature laser grade surface specifications. 1. The harmonics of Nd:YAG and Nd:YVO 4 lasers are widely used for materials processing as well as for measurement applications. Die Anregung wird ausschließlich durch optisches Pumpen realisiert. The high power Q-switched Nd: yag 1064nm laser is ideal for treating darker in colors (blue, black and green), while 532nm wavelength is effective for brighter ink colors (red, orange and yellow). Neodymium doped: yttrium aluminum garnet (Nd:YAG) lasers are perhaps the most commonly used solid state laser. Der erste, 1960 realisierte Laser war ein Festkörperlaser mit einem Rubinkristall als aktivem Medium. This laser eyewear may provide protection from other laser wavelengths not listed. Home Radiation Detectors - Scintillator Radiation Detectors - CZT Radiation Detectors Interface Electronics Photonics Contact. The wavelength of the Nd:YAG laser is almost 10 times lower than that of the CO 2 laser (1,064 microns compared to 10.6 microns). E‐mail: dermguy@dermguy.com. The treatment mechanically breaks down ink particles without casusing thermal damage, casusing the tattoo to fade with minimal risk of scarring or hypopigmentation. Quantel USA. When the 1064 nm beam is frequency-doubled by a KTP crystal filter, the light starts to travel at a second wavelength, 532 nm. Nd:YAG Laser Line mirrors are available from BK7 or UVFS optical material. Its reduced absorption by water and tissue determines an increased penetrability into the tissues, of 5–10 mm. The effectiveness of the Nd:YAG laser wavelength in achieving its successful clinical outcomes under this protocol may be attributed to a variety of factors as discussed below. The Nd:YAG laser at 1064 nm, can be frequency doubled to 532 nm green light. Laser Output Couplers are available with design wavelengths of 532nm or 1064nm for use with Nd:YAG lasers. The shorter wavelength allows significantly smaller foci and thus higher intensities at the same power compared to CO 2 lasers. The medium is a rod composed of neodymium ions and crystals of yttrium-aluminum-garnet. [3] However, there are also transitions near 940, 1120, 1320, and 1440 nm. Q-switched Nd:YAG lasers are an excellent choice for tattoo removal because the 1064 nm wavelength produced is absorbed well by black tattoos and other tattoo colors. The rods allow the Q-Switched lasers to produce different wavelengths. In Q-switched mode, Nd:YAG produces 2 wavelengths, one in the infrared range (1064 nm) and the second beam of 532 nm wavelength which is useful for superficial skin lesions. Dieser Lasertyp zeichnet sich durch einen relativ einfachen kompakten Aufbau aus. On these pages we introduce dual wavelength mirrors and separators for the fourth (266nm) and fifth harmonic (213nm). Correspondnce to: Eric F. Bernstein, MD, MSE, 32 Parking Plaza, Suite 200, Ardmore, PA 19003. Der Erbium-YAG-Laser (auch Erbium:YAG-Laser oder Er:YAG-Laser) ist ein in der Medizin (Dermatologie; Zahnmedizin) verbreiteter Lasertyp, der ein Erbium-dotiertes YAG-Kristall als Lasermedium verwendet. Many Nd:YAG laser systems incorporate a HeNe laser for aligning the beam and locating the focused spot. Laser line and dual band mirrors are designed to operate at 45° or 0° deg angle of incidence. ExQ-Laser? Standard dimensions are ½ and 1 . The Alexandrite laser has a shorter wavelength than the Diode and Nd: Yag lasers, and has been used effectively for laser hair removal treatment on skin types I-IV, meaning fair and light brown skin types. These systems must use dichroic bending mirrors which reflect both the Nd:YAG wavelength (1.06μ) and the red HeNe wavelength (0.632μ). Nd:YAG is versatile and is used across a broad range of applications. Nd:YAG lasers typically emit light with a wavelength of 1064 nm, in the infrared. YAG lasers and CO2 lasers react very differently on different materials because of the differing wavelengths of the laser beams. Nd:YAG lasers emit light at mid-infrared wavelengths (1320 nm, 1064 nm) with pulse durations in the millisecond range. Frequency-doubled Nd:YAG lasers (wavelength 532 nm) are used for pan-retinal photocoagulation in patients with diabetic retinopathy. The high level threshold and the reflectivity of R>99.5% for s- and p-polarized light, makes them well suitable for all industrial ² application. Laser lines and corresponding wavelengths of the second harmonic of Nd:YAG and Nd:YVO 4 As can be seen, a variety of laser lines in the VIS and NIR can be obtained from these crystals. 1.532nm wavelength: get rid of freckles, eyebrow tattoo, failed eye line tattoo, tattoo , lips line, pigment, telangiectasia in shallow red, brown and pink and etc. O 2 Nd: YAG-Laser . Nd:YAG laser has a wavelength of 1064 nm and has the capability to reach deeper layers of skin tissue than other types of lasers. The Nd:YAG laser was the first type of laser used in urological practice. is newly released Q-Switched Nd:YAG laser therapy system.The system has an optimal clinical treatment effect with following parameter designs:dual-wavelength switching of 1064nm&532nm,pulse width short to 5ns and Energy output up to 1000mJ. They work at wavelengths of 1064nm, which is within the infrared area of the light spectrum. The shorter wavelength makes the treatment more effective on lighter skins and not suitable for darker skins.
