1400 - 1480 nm ridge-waveguide pump lasers with 1 watt CW output power for EDFA and Raman amplification

High power ridge-waveguide (RWG) lasers with emission wavelengths from 1400 to 1480 nm have been developed to meet the demands of high channel density EDFA and Raman amplification systems. Output power levels as high as 1 watt from the RWG device can be effectively coupled to single-mode optical fiber producing ex-fiber powers as high as 710 mW.
