Abstract

We report a highly efficient cryo-cooled eye-safe laser operation of a resonantly-pumped (in-band) Er3+:GdVO4 single crystal. The maximum continuous wave (CW) power of 10.3 W with 84% slope efficiency was achieved at 1598.7 with pumping at 1538.6 nm by a spectrally-narrowed Er-fiber laser. Under the 1529 nm resonant pumping by a commercially available diode bar stack operating in a quasi-CW (QCW) mode, the laser delivered 37 W of output power with 68% slope efficiency. This is believed to be the first reported cryo-cooled Er3+:GdVO4 laser, resonantly-pumped into the 4I15/24I13/2 transition.
