Coherent combining of ns-pulse fiber laser sources to > 110W at 1550nm
Abstract
We report on the active coherent beam combination of five large-core Er-doped fiber amplifiers in nanosecond-pulse regimes applicable to LiDAR. We obtain a combined output average power in excess of 100 W at ~ 1550nm-wavelength with excellent spectral and spatial quality.
