In order to obtain the output characteristic of a frequency doubled Yb:YAG laser,a 0.1 atom fractiom doped Yb:YAG microchip crystal(4mm×1mm) end-pumped by laser diodes,and a LBO crystal were employed.With the pump power of 1.37W,frequency selected of nonlinear crystal was realized by tuning the lying angle of LBO 3.1mW TEM00 continuous wave laser at 537.8nm was obtained.The ellipticity of the output beam was 0.94.The results show that high-quality 537.8nm green laser can be obtained with intra-cavity frequency double crystal LBO and Yb:YAG laser crystals.
