Nd:YAG Crystal

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:YAG crystal has higher efficiency and more easy to realizes than Nd:YVO4 crystal blue laser. Nd:YAG crystal was also widely used in 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 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.
Now, we are able to supply the quality of Nd;YAG rods with high optical homogeneity, consistent performance, high processing accuracy and on time delivery.
