Abstract

We report an efficient room-temperature operation of a resonantly pumped Er3+:GdVO4 laser at 1598.5nm. The maximum continuous wave (CW) output power of 3.5W with slope efficiency of 56% was achieved with resonant pumping by an Er-fiber laser at 1538.6nm. With pumping by a commercial laser diode bar stack, a quasi-CW (QCW) output of 7.7W and maximum slope efficiency of 53% versus absorbed pump power were obtained. This is believed to be the first resonantly (in-band) pumped, room-temperature Er3+:GdVO4 laser.
