Nd:YVO4 Laser Crystal
Description
Nd-doped YVO4 crystal is an excellent laser crystal for making the diode-pumped solid lasers. The main and greatest advantages of Nd: YVO4 are high absorption coefficient, big stimulated emission cross-section and wide absorption band, the absorption peak is about 808 nm. Because of these advantages, small crystal can be used to make smaller laser device. The another feature of Nd: YVO4crystal is this uniaxial, which makes it emit linearly polarized lights. Combining with frequency-doubled crystal, all-solid-state lasers with green, blue and red wavelength can be realized.
