摘要A widely tunable cw diode-pumped room-temperature Tm:GdVO4 laser is built. Output power of 2.8W and a slope efficiency of 22% pumped by a 18W Fibre-coupled diode laser at 795nm have been obtained. Continuous tunability from 1820nm to 1946nm is achieved. In addition, the factors that contribute to the efficiency of oscillation are studied.
