Nd:YAG
Neodymium-doped yttrium aluminum garnet (Nd:YAG) is the most commonly used solid-state laser crystal, with high gain, low laser threshold, high efficiency, low loss in the 1064 nm band, good thermal conductivity and thermal shock resistance, high mechanical strength and high optical quality. It is suitable for CW, pulsed, Q-switched, mode-locked and other operating modes. Zhongce can provide round rods or slabs with Nd doping concentrations of 0.3~2.0 at.%.
