Nd:YAG(Neodimium Doped Yttrium Aluminum Garnet) crystals are the most widely used solid state laser materials today. PHOSCTECH offers Nd: YAG rods with high optical homogeneity, consistent performance, high processing accuracy and on time delivery. A variety of specifications and sizes from φ3 x 0.5mm to φ12 x 150mm are available.
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
