Nd:YVO4

The Nd:YVO4 crystal is characterized with large stimulated emission cross-sections at both 1064nm and 1342nm, and higher stimulated emission cross-section of an a-axis cut Nd:YVO4 crystal at 1064nm, about 4 times higher than that of the Nd:YAG crystal.

Nd:YVO4 is one of the most efficient laser host crystal for diode laser-pumped solid-state lasers by means of the following exceptional properties:

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 tendency to single mode output
