Nd:GdVO4

Nd:GdVO₄ Crystals

Nd:GdVO4 is ideal for laser diode pumping, the laser working material which is all-solid-state and micro-miniature lasers, has better thermal conductivity and higher output power than Yttrium Vanadate, so in high-power DPSS applications, the effect of using Nd:GdVO4 will be Better than using Nd:YAG and Nd:YVO4

 Advantages:
  • Low lasing threshold and high slope efficience
  • Large stimulated emission cross-section at lasing wavelength
  • High absorption over a wide pumping wavelength bandwidth
  • Optical uniaxial and large birefringence, emits polarized laser
  • Large thermal conductivity, ~ twice of that of Nd:YVO₄
