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.
