Creating High-Precision Glass for NIR Lasers

Erbium (Er) doped phosphate glass exhibits many beneficial properties, which has led to an increased demand in recent years for Er:glass lasers for applications as wide-ranging as laser rangefinding, long-distance communications, dermatology, and laser-induced breakdown spectroscopy (LIBS). Erbium fiber amplifiers enable rapid global communication in the transpacific cable between Hong Kong and Los Angeles, Er:glass laser rangefinders are increasingly used in defense applications and reconnaissance, and Er:glass aesthetic lasers are gaining traction for removing scarring and even treating hair loss caused by androgenetic alopecia.
