We depend on sturdy technical force and continually create sophisticated technologies to meet the demand of Achromatic Lens, Achromatic Lens, Mgo:Ln Pockels Cell, We believe in quality over quantity. Before export of the hair there is strict quality control check during treatment as per international quality standards.
OEM China Ylf - 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.

Contact us for the best solution for your application of Nd:YAG crystals.
