Neodymium Doped Yttrium Orthvanadate (Nd:YVO4)
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:YVO4 crystal 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.

Frequently Asked Questions
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 devices.
The physical and chemical properties of Nd:YVO4 crystal include zircon tetragonal, space group D4h-I4/amd, density of 4.22g/cm3, melting point of 1825, absorption coefficient of 1.0 cm-1 j 7 cm-1, thermal conductivity of 5.2/(W·m-1·K-1@25°C), thermal optical coefficient(dn/dT), and thermal expansion of 8.5×10-6/K.
Nd:YVO4 crystal is an excellent laser crystal for making diode-pumped solid lasers. It is used in various applications such as 457nm laser, holography, 671nm laser, military field, medical test, and materials processing.
The damage threshold of Nd:YVO4 crystal is greater than 1 for 1064nm, TEM00, 10ns, 10Hz (AR-coated).
Nd:YVO4 crystal is 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.
