Nd:YVO4 is one of the most efficient laser host crystal currently existing for diode laser-pumped solid-state lasers. Nd:YVO4 is an excellent crystal for high power, stable and cost dpss laser.
- Low lasing threshold and high slope efficiency
- Large stimulated emission cross-section at lasing wavelength
- High absorption over a wide pumping wavelength bandwidth
- Optically uniaxial and large birefringence emits polarized laser
- Low dependency on pumping wavelength and tend to single mode output
Basic Properties:
The Sellmeier equations (l in µm):
no2=3.77834+0.069736/(l2-0.04724)-0.0108133.l2
ne2=4.59905+0.110534/(l2-0.04813)-0.0122676.l2
