摘　　要：A high power cryogenic cooling Tin-doped （2%） GdVO4 laser double-end-pumped by fiber-coupled-diode： with the center wavelength of 804.5 nm at 21 ℃ is reported. The highest continuous-wave （CW） power of 2.35 W at 1903 nm is attained at pump power of 24 W. The slope efficiency is 12.5% and the tt, reshoht is 3.2 W. Single- and double-end-pumped types are investigated.A high power cryogenic cooling Tin-doped （2%） GdVO4 laser double-end-pumped by fiber-coupled-diode： with the center wavelength of 804.5 nm at 21 ℃ is reported.
