Abstract

μWe report on a high-power semi-ruggedized laser source, which can deliver radiation in all infrared transmission bands from 2 to 10 μm. In the source a 70 W Tm-doped fiber laser pumps a Q-switched Ho:YAG laser, which produces 37 W of output power at 2.1 μm. The Ho-laser pumps two ZnGeP₂ OPOs. The first generates a combined power of 14 W at 3.9 μm and 4.5 μm, and the second generates watt-level outputs at 2.8 μm and 8 μm. The OPOs have a novel V-shaped 3-mirror ring resonator design, which gives high efficiency and beam quality.
