Abstract

Absorption and emission spectra of Er3+:LuVO4 for the 4I15/24I13/2 transitions have been investigated at room and cryogenic temperatures. A corrected energy level diagram was built. An efficient, resonantly pumped Er3+:LuVO4 laser operating at 1609 nm (π-polarization) or 1597.5 nm (σ-polarization) was demonstrated. For CW pumping into the 1532 nm absorption line by a narrow-bandwidth Er-fiber laser, the maximum output power was ~4.6 W and the maximum slope efficiency was 64% - the best reported efficiency of Er-doped vanadate lasers at room temperature. Resonant pumping into the 1529 nm absorption band with a fiber-coupled diode laser yielded a 62% slope efficiency. To the best of our knowledge, this is the first report on an Er:LuVO4 laser.
