摘　　要：We reported on an efficient high-power continuous-wave laser operation on the^(3)H_(4)→^(3)H_(5) transition of Tm^(3+)ions in a diffusion-bonded composite YVO_(4)/Tm:GdVO_(4)crystal.Pumped by a laser diode at 794 nm,a maximum output power of 7.5 W was obtained from a YVO_(4)/Tm:GdVO_(4)laser at 2.29μm,corresponding to a slope efficiency of 40.3%and exceeding the Stokes limit.To the best of our knowledge,this result represents the maximum power ever achieved from a Tm laser at 2.3μm.
