Nd:YVO4 Crystal
 


Nd:YVO4 crystal is one of the most excellent laser host materials. It is suitable for diode laser-pumped solid state laser. The main features of the crystal are low lasing threshold and high slope efficiency, Large stimulated emission cross-section, High absorption over a wide pumping wavelength bandwith, easy tuning for single mode and high tolerance for pumping wavelength.
Recent developments have proved that Nd:YVO 4 micro-lasers can produce powerful and stable IR and green or red laser with the design of Nd:YVO 4 +KTP.

Advantages:
High absorption over a wide pumping wave length bandwidth.
Large stimulated emission cross-section at lasing wavelength.
Lower lasing threshold and higher slope efficiency.
Low dependency on pumping wavelength and tend to single mode output.
Optically uniaxial and large birefringence emitstrongly-polarized laser.
