Nd:YAG (neodymium-doped yttrium aluminum garnet; Nd:Y 3 Al 5 O 12) is a crystal that is used as a lasing medium for solid-state lasers. The dopant , neodymium in the +3 oxidation state, Nd(III), typically replaces a small fraction (1%) of the yttrium ions in the host crystal structure of the yttrium aluminum garnet (YAG), since the two ions are ...

The first laser, invented by Theodore Maiman in May 1960. Nd:YAG laser: 1.064 μm, (1.32 μm) Flashlamp, laser diode: Material processing, rangefinding, laser target designation, surgery, tattoo removal, hair removal, research, pumping other lasers (combined with frequency doubling to produce a green 532 nm beam). One of the most common high ...

Examples of solid-state laser media include Nd:YAG, Ti:sapphire, Cr:sapphire (usually known as ruby), Cr:LiSAF (chromium-doped lithium strontium aluminium fluoride), Er:YLF, Nd:glass, and Er:glass. Solid-state lasers are usually pumped by flashlamps or light from another laser. Semiconductors, a type of solid, crystal with uniform dopant ...
The Nd-YAG laser emits infrared light at 1.064 micrometres and is the most popular solid-state laser (i.e. laser based on a solid medium). Neodymium glass (Nd:glass) is produced by the inclusion of neodymium(III) oxide (Nd 2 O 3) in the glass melt.
The generation lasers are short pulse (from tens of nanoseconds to femtoseconds) and high peak power lasers. Common lasers used for ultrasound generation are solid state Q-Switched Nd:YAG and gas lasers (CO 2 or Excimers). The physical principle is of thermal expansion (also called thermoelastic regime) or ablation. In the thermoelastic regime ...
The laser is intended to selectively remove diseased or infected pocket epithelium from the underlying connective tissue. The Nd:YAG laser has been shown to reduce levels of microbial pathogens in periodontal pockets [3] and vaporize the pocket-lining epithelium without causing damage to the underlying connective tissue.
