摘　　要：测量了Ｙｂ∶ＹＡＧ晶体的光谱特性，用Ａｒ＋离子泵浦钛宝石激光器作为泵浦源泵浦Ｙｂ∶ＹＡＧ晶体，采用平平腔设计，当输出耦合镜Ｔ１．０５３μｍ＝４．２６％，泵浦功率为１４１０ｍＷ时，得到３２０ｍＷ１．０５３μｍ的高效ＣＷ激光输出，斜率效率为５４％。The absorption and emission spectra of Yb∶YAG are measured at room temperature,which showed that it has two strong absorption peaks at 938nm with a FWHM of 18nm and 968nm with a FWHM of 4nm and broad emission lines It is developed an efficient room temperature 10at% Yb∶YAG microchip laser operating at 1 053μm pumped by a Ti:Sapphire laser operating at 940nm,Ti:Sapphire laser was chosen because of its excellent beam quality,its tunable narrow linewidth and the good overlap between pumped beam and TEM 00 Laser resonator was formed from flat flat cavity The out put coupler reflectivity at 1 053μm was 95 74% The extrapolated threshold was 203mW,and 320mW of 1 053μm CW output power was obtained for an absorbed pump power of 792mW
