2. Nd:YAG laser - Wikipedia

   en.wikipedia.org/wiki/Nd:YAG_laser

   Nd:YAG laser with lid open showing frequency-doubled 532 nm green light Nd:YAG laser rod. 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.

3. Neutral-density filter - Wikipedia

   en.wikipedia.org/wiki/Neutral-density_filter

   ND filters find applications in several high-precision laser experiments because the power of a laser cannot be adjusted without changing other properties of the laser light (e.g. collimation of the beam). Moreover, most lasers have a minimal power setting at which they can be operated.

   F-center laser 2.3-3.3 μm Ion laser Spectroscopy Optically pumped semiconductor laser 920 nm-1.35 μm Laser diode Projection, life sciences, forensic analysis, spectroscopy, eye surgery, laser light shows. The lasing medium is a semiconductor chip. Frequency doubling or tripling is typically done to produce visible or ultraviolet radiation.

5. Diode-pumped solid-state laser - Wikipedia

   en.wikipedia.org/wiki/Diode-pumped_solid-state_laser

   In other words, a green DPSSL using a 2.5 W pump diode would be expected to output around 500-900 mW of 532 nm light. In optimal conditions, Nd:YVO 4 has a conversion efficiency of 60%, [1] while KTP has a conversion efficiency of 80%. [2] In other words, a green DPSSL can theoretically have an overall efficiency of 48%.

6. Neodymium compounds - Wikipedia

   en.wikipedia.org/wiki/Neodymium_compounds

   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.

7. Laser pumping - Wikipedia

   en.wikipedia.org/wiki/Laser_pumping

   A dye laser tuned to 589nm (amber yellow), pumped with an external, frequency-doubled Nd:YAG laser @ 532nm (yellowish-green). The closeness between wavelengths results in a very small Stokes shift, reducing energy losses. A laser of a suitable type can be used to pump another laser. The pump laser's narrow spectrum allows it to be closely ...
