Abstract

We report a three-channel, spectrally beam-combined (SBC), 1μm fiber laser that produces 522W of average power with near-diffraction-limited (M21.2) beam quality. The laser features a SBC power combining efficiency of 93%, versatile master-oscillator, power-amplifier fiber channels with up to 260W of narrowband, polarized, and near-diffraction-limited output that is tunable over nearly the entire 1μm Yb3+ gain bandwidth, and excellent prospects for significant power scaling. To our knowledge, these results represent the highest beam quality and average power achieved to date for a beam-combined fiber laser system.
