Nd:YAG Crystals

Neodymium Doped Yttrium Aluminum Garnet - Nd:YAG laser crystal is the most popular lasing media for solid-state lasers. Good fluorescence lifetime, thermal conductivity and robust nature make Nd:YAG laser crystal suitable for high power continuous wave, high intensity q-switched and single mode operation. EKSMA OPTICS offers high optical quality standard sizes Nd:YAG laser crystals - rods with high damage threshold AR@1064 nm coatings.
