Nd: Ce: YAG Laser Crystals

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, low threshold, anti-violet radiation for lasers operation. As a result-thermal distortion in Nd:Ce:YAG is appreciably less and the output lasers energy is greater (20%-40%) than that in Nd:YAG at the same pumping. It is the most ideal laser material for the air cooling lasers. It is suitable for different modes of operation( pulsed, Q-switched,mode locked) and high-average power lasers.
