Laser Crystal Nd YVO4 Single Axis Crystal Output Is linearly Polarized

Products Description:

Laser Properties: The Nd:YVO4 crystal has large stimulated emission cross-sections at both 1064nm and 1342nm. The stimulated emission cross-section of an a-axis cut Nd:YVO4 crystal at 1064nm is about 4 times higher than that of the Nd:YAG crystal. Although the lifetime of Nd:YVO4 is about 2.7 times shorter than that of Nd:YAG. Because of its high pump quantum efficiency, the slope efficiency of Nd:YVO4 can be very high if the laser cavity is properly designed. In the following Table lists the major laser properties of Nd:YVO4 in comparison with those of Nd:YAG.
