2. Nd:YAG laser - Wikipedia

   en.wikipedia.org/wiki/Nd:YAG_laser

   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 ...

   A "competition" series is chambered in 9mm, 10mm Auto, .40 S&W, and .45 ACP with a 5.25-inch (133 mm) barrel, remotely resembling the tactical XD pistols with 5-inch (130 mm) barrels. An XD series pistol chambered in .40 Smith & Wesson at the Tula State Museum of Weapons

5. Neutral-density filter - Wikipedia

   en.wikipedia.org/wiki/Neutral-density_filter

   In photography and optics, a neutral-density filter, or ND filter, is a filter that reduces or modifies the intensity of all wavelengths, or colors, of light equally, giving no changes in hue of color rendition.

6. Neodymium-doped yttrium orthovanadate - Wikipedia

   en.wikipedia.org/wiki/Neodymium-doped_yttrium...

   Neodymium-doped yttrium orthovanadate (Nd:YVO 4) is a crystalline material formed by adding neodymium ions to yttrium orthovanadate. It is commonly used as an active laser medium for diode-pumped solid-state lasers. It comes as a transparent blue-tinted material. It is birefringent, therefore rods made of it are usually rectangular.

7. Neodymium-doped yttrium lithium fluoride - Wikipedia

   en.wikipedia.org/wiki/Neodymium-doped_yttrium...

   Neodymium-doped yttrium lithium fluoride (Nd:YLF) is a lasing medium for arc lamp-pumped and diode-pumped solid-state lasers. The YLF crystal (LiYF 4 ) is naturally birefringent , and commonly used laser transitions occur at 1047 nm and 1053 nm.

9. QSZ-92 - Wikipedia

   en.wikipedia.org/wiki/QSZ-92

   The decision to develop a new pistol was made in 1987 to replace the Type 54/64/77. [4] Research and development started in 1992. [4] Development of the QSZ-92 pistol began in 1994 and was adopted by the People's Liberation Army's forces in 1998. The export variants (9×19mm versions) include the CF-98 (barrel life c. 8,000 rds) and the NP-42 ...
