Nd:YAG (Neodymium Doped Yttrium Aluminum Garnet, Nd:Y3Al5O12) has been and continues to be the most mature and most widely used crystals for lasers, no matter solid state or lamp pumped, CW or pulsed. It possesses a combination of properties uniquely favorable for laser operations. Nd:YAG
crystals are used in all types of solid-state lasers
systems-frequency-doubled continuous wave, high-energy Q-switched, and
so on.
Nd:YAG Crystal' Advantages
1) High gain, Low threshold, High efficiency
2) High optical quality, Low loss
3) Large mechanical strength,Good thermal conductivity and thermal shock characteristics
4) Suitable for different modes of operation (cw, pulsed, Q-switched, mode locked, doubling of frequency)
5) Suitable for high-average power
lasers
WISOPTIC provides Nd:YAG rods with the following features: different doping levels, high optical homogeneity, high processing accuracy, precise barrel grooving and wedge angle, various end cuts, various dielectric coatings, high damage threshold.
