Applications

Efficient fiber lasers and fiber amplifiers operating in the eye-safe 2um band. High-power continuous-wave and pulsed fiber lasers and amplifiers operating at eye-safe (~2um) wavelengths. Eye-safe industrial and medical fiber lasers. Military and commercial lidar.

Key Features

High pump-conversion efficiency. Pump-cladding NA 0.46 enables efficient pump coupling and delivery; the 55um core supports high output power without parasitic SBS or SRS. Optimized for 793nm pumping for very high conversion efficiency. High pump absorption enables fiber laser output in the ~2um window with shorter fiber lengths.
