Non Standard Nd:YAG Rods

Neodymium-doped yttrium aluminum garnet (Nd:YAG) laser crystals are the most popular laser medium for solid-state lasers. Good fluorescence lifetime, thermal conductivity, and robust properties make Nd:YAG laser crystals suitable for high-power CW, high-intensity q-switching, and single-mode operation. Alfa Chemistry offers a wide range of high optical quality Nd:YAG laser crystals.
