Nd:Ce:YAG Laser Rods

Nd:Ce:YAG crystal is the most ideal laser working material for repetitive frequency air-cooled (or naturally cooled) lasers. The Nd:Ce:YAG laser rod we provide has the characteristics of high efficiency, low threshold, resistance to ultraviolet radiation, and high repetition rate, suitable for various modes of operation (continuous, pulse, Q-switching, mode locking, frequency doubling), reaching the international advanced level.
