Nd:YAG laser crystal is the most early and mature laser material adopted by R&D, medical, industrial and military customers. It is the ubiquitous presence for near-infrared solid-state lasers and their frequency-doubler, tripler, and higher order multiplier.
Advantages:
- High gain, High efficiency, Low threshold, Low loss at 1.06 μm
- Good thermal conductivity and thermal shock characteristics
- Mechanical strength, High optical quality
- Various modes of operation (CW, pulsed, Q-switched, mode locked)
