IPG`s ELR Erbium continuous wave (CW) lasers are exciting products that do not have any analogs on the market. First manufactured in 1994 for airborne applications, Erbium CW fiber lasers have since been deployed in a vast variety of telecom, R&D, industrial and medical applications.
ELR-LP Series are linearly polarized continuous wave (CW) Erbium fiber lasers with powers up to 30 W. These linearly polarized single-mode lasers provide diffraction limited output in “eye-safe”* (1540-1600 nm) spectral range with all solid-state laser reliability. Their turnkey operation, compact size, and air-cooled simplicity make them ideal IR sources for both commercial OEM and scientific applications.

“Eye-Safe” operation generally means that eye damage threshold is many orders of magnitude higher than for 1 μm lasers. Nevertheless, it is a Class IV laser product. IPG Photonics recommends that appropriate eyewear is worn and laser safety procedures are followed.
