Nd:YVO4
Feature and advantage:
- Low lasing threshold and high slope efficiency
- Low dependency on pumping wavelength and strong tendency to single mode output.
- Large stimulated emission cross-section at lasing wavelength of 1064nm.
- High absorption over a wide pumping wavelength bandwidth
- A uniaxial crystals with large birefringence emit linearly-polarized laser.
PRODUCT
Detail
The neodymium-doped yttrium vanadate (Nd:YVO₄) crystal is a highly performance laser crystal, composed of the dopant ion neodymium (Nd) and the laser matrix yttrium vanadate (YVO₄). It has a strong and wide absorption band near 808nm, with a high absorption coefficient. Its absorption efficiency for pump light is several times that of Nd:YAG, effectively absorbing the pump light emitted by laser diodes (LDs), and selectively absorbing polarized light. When the polarization direction of the pump light is consistent with the laser radiation direction, the absorption is the strongest. The main emission peak wavelength is 1064.3nm, with a large excitation emission cross-section, enabling efficient laser output. The output laser has good polarization characteristics and can output linearly polarized light.
