Nd Doped Phosphate Glass have been widely used in high average power laser solid state lasers, laser material processing, range finder and other industrial strial and scientific applications.

LLG mainly offers two types of Nd3+ doped phosphate glasses-N21 and N31. LLG Nd3+ phosphate glasses are guaranteed in optical qualities such as homogeneity, striation, stress birefringence, Pt inclusions etc. The different n eodymium doping phosphate glass are ready for your quest. We have stocked 0.7%, 3.0%, and 4.0% doped N31 and N21.
