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