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
