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.
Low threshold
Very high slope efficiency(30%-50% more than Nd:YAG)
Good anti-UV irradiation property
Good thermal stability
High optical quality
Flat/flat
Parallel/ anti-parallel wedged
Brewster angle
Concave/convex radii
Cylinder grooved
