| Abstract: | 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 TEM00 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. |
