0.5-1.1atm% dopant Nd YAG Laser Crystal for solid state lasers

Laser Crystal Nd:YAG

Overview:

Invented in the sixties of the last century, Nd:YAG has been and continue to be the most widely used laser crystal for solid-state crystal material. Its laser parameters are a good compromise between the strengths and weaknesses of its competition. Nd:YAG crystals are used in all types of solid-state lasers. Compared with others laser crystals, its fluorescence lifetime is twice more than Nd:YVO4 , and thermal conductivity is also better.
