Schott LG-940 Phosphate Laser Glass
Categories:	Ceramic; Glass; Optical
Material Notes:	The LG-940 is an Erbium – Ytterbium – Chromium – Cerium doped phosphate based laser glass used in flash lamp pumped and diode pumped solid-state laser systems. Phosphate glasses generally offer higher solubility of rare earth dopants, thus the amount of active ions can be significantly increased. Applications Medical lasers for dermatological use Analytical instrumentation Rangefinders Advantages Good athermal properties High transmission at the lasing wavelength Consistent quality and high homogeneity Information provided by SCHOTT.
