Nd YAG

Nd:YAG crystal is the most commonly used solid-state crystal material, it is characterised by high gain, low threshold, high efficiency, low loss at 1064nm high optical quality, good mechanical and thermal properties, easy to operate in TEM00 mode, make it used in all types of solid-state lasers systems, compared with others laser crystals, its fluorescence lifetime is twice more than Nd:YVO4, and thermal conductivity is also better.


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)
