Highly efficient Ho: YAP laser with 202 W of linearly polarized output power at 2118 nm

Highly efficient Ho: YAP laser with 202 W of linearly polarized output power at 2118 nm

We report on high power and efficient operation of a compact Ho: YAP laser in-band pumped at 1931 and 1943 nm with a high-power and narrow-linewidth Tm-doped fiber laser. Using a 0.5at. % Ho3+ doped Ho: YAP cut along the b-axis and a simple two-mirror resonator, up to 202 W of output power has been...
