High-power diode-side-pumped rod Tm:YAG laser at 2.07 µm.

ABSTRACT

We report a high-power diode-laser (LD) side-pumped rod TmYAG laser of around 2 µm. The laser was water-cooled at 8°C and yielded a maximum output power of 267 W at 2.07 µm, which is the highest output power for an all solid-state cw 2.07 µm rod TmYAG laser reported as far as we know. The corresponding optical-optical conversion efficiency was 20.7%, and the slope efficiency was about 29.8%, respectively.
