High-power Yb:YAG thin-disk laser with 80% efficiency pumped at the zero-phonon line

We report a 3-kW thin-disk laser with 80% optical efficiency employing zero-phonon line pumping at 970 nm. A detailed comparison to conventional pumping at 940 nm is provided, which shows almost twice the pump power density handling capability.
