产品详细介绍：
Neodymium doped Yttrium Aluminium Garnet (Nd:Y3Al5O12 or Nd:YAG) crystal with the excellent thermal-mechanical properties and unique laser properties is by far the most commonly used solid-state laser material. Pumped by Xenon arc lamp or 808nm-LD, Nd:YAG mainly lase at 1064.14nm and run in both pulsed and CW operation. Nd:YAG laser has been widely used in a various applications in the military, scientific, industrial, and medical areas.
