Product Details

Description:

Nd:YAG crystal is the most widely used solid-state laser material today. It has been used in the “micro/mini” “DPSS” (Diode Pumped Solid State” laser system to get high quality Red, Green or Blue laser output in which the blue laser of Nd: YVO4 crystal has higher efficiency and the military, scientific, medical and industrial laser systems, high performance scientific laser systems, laser therapy, cosmetology systems, laser marking, laser drilling and other laser material processing systems. Especially, Nd:YAG crystal is the best laser material for the high power, high energy, and Q-switched pulse laser systems. The very wide applications of Nd:YAG crystal in various laser system is because its outstanding performance in physics and mechanics.
