Paper Abstract

A multipass amplifier for a picosecond Nd:YLF laser was designed and developed for the light source of a laser-Compton X-ray generator. The developed amplifier was constructed of a water-cooled Nd:YLF rod (20mm long, 4mm in diameter) and a pair of quasi-CW laser diodes (peak power 1kW) with optical systems for rod pumping. The amplifier was operated as a laser with a generated output energy of 218mJ and slope efficiency of 31% at 10Hz. We then operated the laser as an amplifier with 0.4mJ, at 10ps, 1047nm seed light. The amplified energy was 4mJ in the single-pass configuration and 3OmJ in the double-pass configuration. The experiment result was compared with the theoretical result derived from the Frantz-Nodvik equation. The results agreed well in the lower energy region but diverged in the higher energy region.
