product description:
Nd, Ce: YAG neodymium-doped and cerium-yttrium-aluminum garnet) laser rod is the most ideal working material for repetitive rate air-cooled lasers. It is suitable for a variety of working methods (pulse, Q-switching, mode locking), and is widely used in small lasers. Ranging, laser medical treatment, laser spot welding, etc.

ND, CE: Advantages of YAG
●High efficiency, low threshold
●High optical quality
●Good anti-ultraviolet radiation properties
●Good thermal stability
●Good repetition frequency characteristics
