Nd YVO4 Laser Crystal Laser Crylink

Nd: YVO4

Nd:YVO4 crystal is an excellent laser for making the diode-pumped solid lasers. The primary and most significant advantages of Nd:YVO4 are high absorption coefficient, significantly stimulated emission cross-section and wide absorption band. The absorption peak is about 808 nm. Because of these advantages, tiny crystals can be used to make smaller laser devices. Another feature of Nd:YVO4 crystal is this uniaxial, which makes it emit linearly polarized lights. It is combined with frequency doubling crystals to enable an all-solid-state laser with green, blue, and red wavelengths.
