Pulsed Laser Free Space 1550nm Erbium Glass

SKU: EDGL

The EDGL Erbium-Doped Glass Laser emits at approximately 1535–1550 nm, an eye-safer wavelength widely used in laser rangefinding and LiDAR applications. Pumped by 980 nm laser diodes, it operates in pulsed Q-switched mode, leveraging the long upper-state lifetime of erbium glass for efficient energy storage and high pulse energy output. The laser produces clean, tail-free pulses with stable pulse energy and excellent single mode beam quality. The semiconductor pump module and laser crystal are integrated into a compact, rugged package for easy installation and system integration. A compatible driver is available for fast evaluation, and an optical filter can be incorporated into the package as an option.
The wall-plug (electrical-to-optical) efficiency is about 10%. The device has no active cooling and requires a heat sink for proper thermal dissipation. A demo driver is available for evaluation the performance.
The EDGL can be manufactured in the USA using domestically produced pump lasers.
