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.  Nd:Ce:YAG laser crystal 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.
