NdCeYAG

 Nd:Ce:YAG crystal is an excellent laser material used for no-water cooling and miniature laser systems. The (Nd, Ce): YAG laser rod we produce has the characteristics of high efficiency, low threshold, anti-violet radiation and high repetition frequency for lasers operation. It has achieved the international advanced level. It is the most ideal laser material for the high repetition air cooling lasers. It suitable for different modes of operation (CW, pulsed , Q-switched, mode locked, doubling of frequency ) and high-average power lasers
 

Advantages:


1. Low threshold
2. Very high slope efficiency
3. Good thermal stability
4. High optical quality
5. Good anti-UV irradiation property
