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.

Electro-optic deflectors (EODs) are optical devices used to steer or deflect light beams by applying an electric field to a specialized optical crystal. Unlike mechanical beam steering systems that rely on moving mirrors, electro-optic deflectors enable high-speed, non-mechanical beam control with exceptional precision and responsiveness. They are widely used in laser scanning, optical communications, microscopy, laser printing, spectroscopy, and scientific research, where rapid and accurate laser beam positioning is essential.
