Abstract

We report on a high-average-power, high-energy cryogenic Ho:YLF picosecond chirped-pulse amplification system operating at 1 kHz repetition rate. High gain characteristics and excellent thermal management were well achieved by integrating cryogenic cooling with in-band pumping. A maximum compressed average power of 205 W at 1 kHz repetition rate with a pulse duration of 1.7 ps was delivered by the system. A high extraction efficiency of 41.2% and near-diffraction-limited beam quality (M 2 = 1.14) were demonstrated.
