2020 Latest Design Dkdp Crystal - Nd:YAG Crystal – WISOPTIC
2020 Latest Design Dkdp Crystal - Nd:YAG Crystal – WISOPTIC Detail:
Nd:YAG (Neodimium Doped Yttrium Aluminum Garnet) has been and continue to be the most widely used laser crystal for solid-state lasers. Good fluorescence lifetime (twice more than that of Nd:YVO4) and thermal conductivity, as well as robust nature, make Nd:YAG crystal very suitable for high-power continuous wave, high-energy Q-switched and single mode operations.
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.
