Paper Abstract

We report what is believed to be the first laser operation based on Ho3+-doped YVO4. The Ho+3: YVO4 was resonantly diode-pumped at ~1.93 μm to produce up to 1.6 W of continuous wave (CW) output power at ~2.054 μm. The laser had a slope efficiency of ~38% with respect to absorbed power. We have measured the absorption and stimulated emission cross sections of The Ho+3: YVO4 at 77 K and present the calculated gain cross section spectrum at 77 K for different excited state inversion levels.
