Abstract

We report on a compact efficient highrepetitionrate 100 kHz optically pumped AlGaInAs nanosecond eyesafe laser at 1525 nm A diamond heat spreader bonded to the gain chip is employed to improve the heat removal At a pump power of 133 W the average output power at a repetition rate 200 kHz is up to 312 W corresponding to a peak output power of 560 W At a repetition rate 500 kHz the maximum average power and peak power are found to be 232 W and 170 W respectively
