Er:glass series laser is RealLight’s self-developed, designed, manufactured diode laser pumped passively Q-switched laser based on erbium glass as laser gain medium, Er:glass laser also called eye-safe laser, wavelength is 1535nm, which can effectively inhibit the damage of laser to retina. Repetatin rate from 1Hz to 10kHZ optional, output energy from 5μJ to 2mJ optional, utilize diode laser packing process, intergrating pumping module and laser crystal with full sealed design.It has features of small size, light weight(≥8g),wide temperature operation(-40~65℃), etc. It is widely used in eye-safe range finder, material analysis and other fields.
