23-watt 77% efficient CW OPO pumped by a fiber laser

We have demonstrated 23 Watts total output power from a CW OPO. We believe this to be the highest total power output yet demonstrated from this class of device. The OPO was based on MgO-doped PPLN and was pumped by a 30 Watt fiber laser. The external efficiency was 77 % and the corresponding pump depletion was 83%. Output of 16.8 Watts at 1.5 microns and 6.2 Watts at 3.6 microns was demonstrated. We have also demonstrated simultaneous output of 10 Watts at 1.96 microns and 8 Watts at 2.34 microns in the same device.
