We analyzed the spectroscopic performances of Yb:YAG and developed an efficient room-temperature 20at.% Yb:YAG thin chip (6×6×0.5 mm) laser operating at 1.053μm pumped by Ti-sapphire laser operating at 940n... We analyzed the spectroscopic performances of Yb:YAG and developed an efficient room-temperature 20at.% Yb:YAG thin chip (6×6×0.5 mm) laser operating at 1.053μm pumped by Ti-sapphire laser operating at 940nm. Output power of 356 mW was obtained for an absorbed pump power of 784 mW. The slope efficiency was 69%, and the extrapolated threshold was 273mW. The slope efficiency was as high as 72% with absorbed pump power exceeding 730 mW. 展开更多
