The Resonantly Diode Pumped, Cryogenic Ho3+:YVO4 2.05-Micrometers Laser

Abstract

We report what is believed to be the first laser operation based on Ho(3+)-doped yttrium orthovanadate (YVO(4)). The cryogenic (77 K) Ho(+3):YVO(4) was resonantly diode-pumped at approximately 1.93 microns to produce up to 1.6 W of continuous wave (CW) output power at approximately 2.054 microns. The laser had a slope efficiency of approximately 38% with respect to absorbed power. We have measured the absorption and stimulated emission cross sections of the Ho(+3):YVO(4) at 77 K, 175 K, and 300 K and present the calculated gain cross section spectrum at 77 K for different excited state inversion levels.
