Nd:YAG


Nd:YAG(Neodimium Doped Yttrium Aluminum Garnet) has been widely used laser crystal for solid-state laser. Its laser parameters are a good compromisebetween the strengths and weaknesses of its competition. Nd:YAG crystals are used in all types of solid-state lasers 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.

The Sellmeier equations (l in µm for YAG):

n ^2 = 2.08745 + 1.2081 l ^2 /(l^ 2 - 0.02119 )+ 17.2049 l ^2 /(l ^2 - 1404.45 )

Applications:

Nd:YAG can produce blue laser with the frequency-doubling of 946nm

Nd:YAG can be operated in a very high power laser up to kw level at 1064nm

Nd:YAG can be Q-switched with Cr4+YAG directly

Nd:YAG can be used for high power green laser for SHG@1064nm
