PREPARED BY :~ Nd ion is rare earth metal and it is doped with solid state host crystal like yttrium aluminium garnet (YAG – Y 3 Al 5 O 12) to form Nd:YAG laser. Laser Types in Retina Argon blue-green laser (70% blue (488 nm) and 30% green(514nm)) Absorbed selectively at retinal pigment epithelial layer (RPE), hemoglobin pigments, choriocapillaries, inner and outer nuclear layer of the retina. • 1961: First HeNe laser, then rapid invention of most lasers … • 1977: Gordon Gould awarded the patent for the laser. Over 90 percent of patients had malignant tumors. Enrollment no. Prepared by : For bacterial reduction, the laser parameters were … Nd:YAG laser energy exhibits color . Due to doping, yttrium ions get replaced by the Nd 3+ ions. Clipping is a handy way to collect important slides you want to go back to later. The fiberoptic bronchoscope (FOB group) was used exclusively during the first two years (61 cases, 32 patients).

The Nd:YAG laser (PerioLase MVP-7) is at the heart of the Laser-Assisted Peri-Implantitis Procedure (LAPIP) that is based on the successful LANAP (Laser-Assisted New Attachment Protocol) therapy. is absorbed by water. The Nd:YAG laser is the most common laser used in laser designators and laser rangefinders. See our User Agreement and Privacy Policy. Nd YAG laser was discovered in 1964 by the J.E. See our User Agreement and Privacy Policy. : 4 Normally, we used power settings ranging from 40 to 50 W with pulse duration of 0.7-1.2 s. A number of groups have demonstrated the efficacy of neodymium:yttrium-aluminum-garnet (Nd:YAG) laser bronchoscopy for treatment of patients with selected tracheobronchial disorders. These lasers have many different applications in the medical and scientific field for processes such as Lasik surgery and laser Geusic at Bell laboratory in USA. Van Vitert in 1964. All except four of these cases utilized conscious sedation and local anesthesia.
