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
