DESCRIPTION
The Erbium Glass Laser is a type of laser that uses erbium as the activating ion and ytterbium as the sensitizer in a laser glass medium. ERDI has developed and produced a 1535nm Microchip Laser Module that incorporates a proprietary erbium-doped glass with a refractive index of 1.54 µm and doping concentrations of erbium (0.1–3.0) × 10¹⁹ and ytterbium (1.5–3.0) × 10²¹, resulting in a fluorescence lifetime of 8–10 ms. It is widely used in applications such as laser ranging, laser irradiation, LIDAR, target recognition, laser medicine, and fiber optic communication.
