ERDI's newly launched MINI-type 1535nm erbium-doped glass laser uses co-doped Er:Yb phosphate glass and a semiconductor laser pump source. It is a Class 1 eye-safe laser, with dimensions of only 14.5×6.3×4.37 mm³ and a weight of 2.5g. The pulse energy is ≥100μJ, and the pulse repetition rate is 1-10Hz. It is widely used in laser ranging and lidar.
