| Abstract: | We report on a compact efficient high-repetition-rate (>100?kHz) optically pumped AlGaInAs nanosecond eye-safe 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 13.3?W, the average output power at a repetition rate 200?kHz is up to 3.12?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 2.32?W and 170?W, respectively. |
