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. Due to design constraints, reflectivity can only be maximized at one wavelength. The 532 nm wavelength is very effective on red, pink, orange, and other bright colors. 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). This laser eyewear may provide protection from other laser wavelengths not listed. E‐mail: dermguy@dermguy.com. The medium is a rod composed of neodymium ions and crystals of yttrium-aluminum-garnet. They are one of the most common types of laser, and are used for many different applications. Many Nd:YAG laser systems incorporate a HeNe laser for aligning the beam and locating the focused spot. In certain cases these lasers are also used to treat eye floaters. Nd:YAG (Neodymium Doped Yttrium Aluminum Garnet, Nd:Y 3 Al 5 O 12) has been and continues to be the most mature and most widely used crystals for lasers, no matter solid state or lamp pumped, CW or pulsed.It possesses a combination of properties uniquely favorable for laser operations. O 2 Nd: YAG-Laser . 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. The rods allow the Q-Switched lasers to produce different wavelengths. Standard dimensions are ½ and 1 . It uses a crystal of neodymium that produces a light invisible at a continuous wavelength of 1064 nm. Nd:YAG lasers are optically pumped using a flashlamp or laser diodes. This phenomenon is used to build compact diode pumped solid stated lasers with a variety of wavelengths which are used for measurement applications as well as for projection systems (RGB lasers). [6] Nd:YAG lasers emitting light at 1064 nm have been the most widely used laser for laser-induced thermotherapy, in which benign or malignant lesions in various organs are ablated by the beam. Nd:YAG lasers emit light at mid-infrared wavelengths (1320 nm, 1064 nm) with pulse durations in the millisecond range. 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. Nd:YAG Wavelength The Nd:YAG laser belongs to short laser wavelength, periodontal tissues, ablating the inflamed lesions and has a wavelength of 1,064 nm and operates in a free running pulsed mode. Es kann sowohl kontinuierlich als auch gepulst erfolgen. The Nd:YAG laser crystal was developed not long after the discovery of the ruby laser in the 1960s. It includes a Second-Harmonic-Generation (SHG) module providing an additional output beam at 532 nm. Neodymium:Yttrium Garnet (Nd:YAG) is one of the most widely used lasing media, lasing at wavelengths - 947, 1064 and 1319nm and with a pumping wavelength of 807.5nm. operate at both first and second Nd:YAG laser harmonics; retardation tolerance <λ/300; Dual wavelength multiple order wave plates are made of precisely polished quartz. They not only work at this wavelength, but can also work in a double frequency mode which creates green light at 532nm wavelengths. Selective Photothermolysis. The shorter wavelength makes the treatment more effective on lighter skins and not suitable for darker skins. YAG lasers and CO2 lasers react very differently on different materials because of the differing wavelengths of the laser beams. Nd:YAG lasers operate in both pulsed and continuous mode. Laser line and dual band mirrors are designed to operate at 45° or 0° deg angle of incidence. Nd:YAG is versatile and is used across a broad range of applications. 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. Nd:YAG lasers are solid state lasers. The Nd:YAG laser was the first type of laser used in urological practice. The Nd:YAG Laser System is stabilized on the saturated absorption spectrum of molecular iodine. Die Anregung wird ausschließlich durch optisches Pumpen realisiert. Neodymium doped: yttrium aluminum garnet (Nd:YAG) lasers are perhaps the most commonly used solid state laser. On these pages we introduce dual wavelength mirrors and separators for the fourth (266nm) and fifth harmonic (213nm). Aufgrund seiner physikalischen Eigenschaften können mit Hilfe des Er:YAG-Lasers oberflächliche Strukturen entfernt oder ganz allgemein „bearbeitet“ werden. Nd:YAG Laser Line mirrors are available from BK7 or UVFS optical material. Main Line Center for Laser Surgery, Ardmore, Pennsylvania, 19003 . 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. The system with all its extension options (CA-1231 through CA-1234) is the most flexible DPSS system on the market. Laser Output Couplers are available with design wavelengths of 532nm or 1064nm for use with Nd:YAG lasers. Compared to the CO 2 laser wavelength, the 1.06 μm of the Nd-Yag laser has a very different behaviour concerning its interaction with the vapour plume. Some of the Q-Switched lasers include: Q-Switched Nd: YAG Laser is used mostly for non-ablative skin rejuvenation, darkened scars, brown birthmarks. Quantel USA.

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. Dieser Lasertyp zeichnet sich durch einen relativ einfachen kompakten Aufbau aus. Nd:YAG lasers typically emit light with a wavelength of 1064 nm, in the infrared. Its high gain, narrow linewidth, low threshold and physical properties make it a most versatile laser material for a variety of applications. A novel dual‐wavelength, Nd:YAG, picosecond‐domain laser safely and effectively removes multicolor tattoos. Nd:YAG lasers typically emit light with a wavelength of 1064 nm, in the infrared. They work at wavelengths of 1064nm, which is within the infrared area of the light spectrum. Its extreme stability, compactness, unmodulated output and high power makes it suitable for the calibration of all wavelength meters in the most demanding applications. Of all the solid-state laser crystals, it has stood the test of time best. The treatment mechanically breaks down ink particles without casusing thermal damage, casusing the tattoo to fade with minimal risk of scarring or hypopigmentation. In water, the Nd:YAG laser will theoretically penetrate to a depth of 6 mm before it is attenuated to 10% of its original strength. 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). Der erste, 1960 realisierte Laser war ein Festkörperlaser mit einem Rubinkristall als aktivem Medium. ExQ-Laser? Diode Pumped Nd:YAG Laser (CA-1230) The diode-pumped solid-state laser CA-1230 is a versatile laser source designed for training and educations, but can also be used in research applications. These variable wavelengths determine what the Q-Switched laser will be used for. The Nd:YAG laser at 1064 nm, can be frequency doubled to 532 nm green light. 340 laser safety glasses were primarily developed for protection from laser wavelengths 950-10,600 nm: Diode, Fiber Optic Diodes, Nd:YAG, Er:YAG, Ho:YAG, CO2 (980 nm, 1,064 nm, 2,780 nm, 2,940 nm, 2100 nm, 10,600 nm). Frequency-doubled Nd:YAG lasers (wavelength 532 nm) are used for pan-retinal photocoagulation in patients with diabetic retinopathy. Its reduced absorption by water and tissue determines an increased penetrability into the tissues, of 5–10 mm. The Nd:YAG laser line mirrors are offered for 0° and 45° application. 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. integrated with real-time energy monitor,energy auto-changing by adjustable handpiece,water filtration … Thickness of the plate is controlled to provide the specified retardation at two wavelengths. 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.
