Schott LG-770 Phosphate Laser Glass
Categories: Ceramic; Glass; Optical

Material Notes: LG-770 is an aluminum-phosphate based glass with a high cross section for stimulated emission, extremely low nonlinear refractive index, and good athermal characteristics. This glass was initially developed for the US DOE National Ignition Facility and French CEA Project Laser Megajoule. The development and the advantages of this glass are discussed in “Laser and thermo-physical properties of Nd-doped phosphate glasses” Proc SPIE, Vol 1761, 162- 173 (1992).
