Nd:YVO4 Crystal

Nd:YVO4 crystal is one of the most excellent laser host materials, it is preferable for diode laser-pumped solid state laser. The crystal has these many  typical  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.
Applications and Advantages:
  • Lower lasing threshold and higher slope efficiency;
  • High absorption over a wide pumping wavelength bandwidth;
  • Low dependency on pumping wavelength and tend to single mode output;
  • Large stimulated emission cross-section at lasing wavelength;
  • Preferable-polarized laser generation;
