Abstract
We present a laser amplifier based on coherent combination of 16 channels from a single multicore fiber employing multi-channel components for beam splitting, combination and temporal phasing. Stretched femtosecond pulses (250 fs transform-limit) were combined with an efficiency of 80% at up to 205 W average power.
