Nd:YAG

basic information
Product Details

Nd:YAG

Nd:YAG is the most widely used solid state laser crystal. It is mainly used in industrial, medical, military and scientific applications. It has the characteristics of high gain, low threshold, high efficiency, high optical quality, low loss, large mechanical strength, good thermal conductivity and thermal shock characteristics.It’s suitable for different applications (CW, pulsed, Q-switched,, mode locked, frequency doubling) and high-average power lasers.
