Nd:Ce:yag laser rod,yag crstal
Nd:Ce:YAG 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( laser efficiency than Nd: YAG high about 30-50%), 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
