|
Nd:YAG (Neodimium Doped Yttrium Aluminum Garnet) has been widely used laser crystal for solid-state laser. 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 systems-frequency-doubled continuous wave, high-energy Q-switched , etc.. Compared with others laser crystals, its fluorescence lifetime is twice more than Nd:YVO4, and thermal conductivity is also better.
