A diode-pumped solid-state laser (DPSSL) is a solid-state laser made by pumping a solid gain medium, for example, a ruby or a neodymium-doped YAG crystal, ...
A laser of a suitable type can be used to pump another laser. The pump laser's narrow spectrum allows it to be closely matched to the absorption lines of the lasing media, giving it much more efficient energy transfer than the broadband emission of flashlamps. Diode lasers pump solid state lasers and liquid dye lasers.
A laser diode (LD, also injection laser diode or ILD or semiconductor laser or diode laser) is a semiconductor device similar to a light-emitting diode in which a diode pumped directly with electrical current can create lasing conditions at the diode's junction.
A green laser pointer is a frequency doubled Nd:YVO 4 diode-pumped solid state laser . [48] Nd:YAG can be also made to lase at its non-principal wavelength. The line at 946 nm is typically employed in "blue laser pointer" DPSS lasers, where it is doubled to 473 nm. [49] [50] [51]
Flashlamp, laser diode: Periodontal scaling, dental laser, skin resurfacing Neodymium YLF solid-state laser 1.047 and 1.053 μm Flashlamp, laser diode Mostly used for pulsed pumping of certain types of pulsed Ti:sapphire lasers, combined with frequency doubling. Neodymium-doped yttrium orthovanadate (Nd:YVO 4) laser 1.064 μm laser diode
Laser rods (from left to right): Ruby, alexandrite, Er:YAG, Nd:YAG. A solid-state laser is a laser that uses a gain medium that is a solid, rather than a liquid as in dye lasers or a gas as in gas lasers. [1] Semiconductor-based lasers are also in the solid state, but are generally considered as a separate class from solid-state lasers, called ...
Optical pumping is a process in which light is used to raise (or "pump") electrons from a lower energy level in an atom or molecule to a higher one. It is commonly used in laser construction to pump the active laser medium so as to achieve population inversion. The technique was developed by the 1966 Nobel Prize winner Alfred Kastler in the ...
In 2012, Nichia and OSRAM developed and manufactured commercial high-power green laser diodes (515/520 nm), which compete with traditional diode-pumped solid-state lasers. [76] [77] Vertical cavity surface-emitting lasers are semiconductor lasers whose emission direction is perpendicular to the surface of the wafer. VCSEL devices typically have ...
