Nd:YAG

Nd:YAG (Neodymium Doped Yttrium Aluminum Garnet) is the most popular lasing media for solid-state lasers. Good fluorescence lifetime and thermal conductivity, as well as robust nature, make Nd:YAG crystal very suitable for high-power continuous wave, high-intensity Q-switched and single mode operations.
Wisoptic offers Nd:YAG rods with the following features: different doping levels, high optical homogeneity, precise barrel grooving, various end cuts, various dielectric coatings, high damage threshold.
