Detailed introduction

Nd:Ce:YAG is an excellent laser material used for no-water cooling and miniature laser systems.The thermal distortion of Nd:Ce:YAG is appreciably less and the output laser energy is greater(30%-50%)than that in Nd:YAG at the same pumping.It is the most ideal laser material for air cooling laser and is also suitable for different modes of operation(pulsed,Q-switched,mode locked)and high-average power lasers.

PRODUCT FEATURE

High slope efficiency,Low threshold

High optical quality

Good anti-UV irradiation property

Good thermal stability

Good repetition frequency
