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 ...
Laser welding of polymers is a set of methods used to join polymeric components through the use of a laser. It can be performed using CO 2 lasers, Nd:YAG lasers, Diode lasers and Fiber lasers. [1] When a laser encounters the surface of plastics, it can be reflected, absorbed or penetrate through the thickness of a component.
YAG laser may refer to two types of lasers that use yttrium aluminum garnet (YAG): Nd:YAG laser (doped with neodymium) Er:YAG laser (doped with erbium
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.
This means the area highlighted by the HeNe laser is not precisely the area being affected Nd:YAG laser, and therefore some surgical lasers have an added adjustment to compensate. [2] The first successful use of photodisruption was in 1972, on a case of trabecular meshwork. [1]
The most basic optical tweezer setup will likely include the following components: a laser (usually Nd:YAG), a beam expander, some optics used to steer the beam location in the sample plane, a microscope objective and condenser to create the trap in the sample plane, a position detector (e.g. quadrant photodiode) to measure beam displacements ...
