Nd:YAG crystal
Baijing supplies Nd:YAG crystals, described in Chinese as neodymium-doped yttrium vanadate, as stated in the source. They are excellent laser crystals for laser-diode-pumped systems, especially at low and medium powers. Compared with Nd:YAG, Nd:YVO4 has a higher pump absorption coefficient and larger stimulated-emission cross-section. Nd:YVO4 lasers are widely used in machinery, material processing, spectroscopy, wafer inspection, displays, medical testing, laser printing, and data storage.

Nd:YVO4 crystal Laser Crystals 100optics
Baijing Optoelectronics supplies Nd:YVO4, neodymium-doped yttrium vanadate, an excellent laser crystal for laser-diode pumping, especially at low and medium powers. Compared with Nd:YAG, Nd:YVO4 has higher pump absorption and a larger stimulated-emission cross-section. Nd:YVO4 lasers are widely used in machinery, material processing, spectroscopy, wafer inspection, displays, medical testing, laser printing, and data storage. The English section describes yttrium vanadate (Nd:YVO4) as one of the most efficient host crystals for diode-pumped solid-state lasers. A large stimulated-emission cross-section at the laser wavelength, high pump absorption and broad pump-absorption bandwidth, high laser-induced damage threshold, and good physical, optical, and mechanical properties make Nd:YVO4 suitable for high-power, stable, cost-effective diode-pumped solid-state lasers. Recent developments show that Nd:YVO4 can produce powerful, stable infrared, green, and blue lasers by combining Nd:YVO4 with frequency-doubling crystals.
