Though the quantitative analysis on the space overlap of laser transverse modes in the active medium,the formula for distribution of laser pump power on variable harmonic transverse modes is obtained.It is found that high harmonic modes in the cavity have great effect on the output beam quality,and the way for reducing the influence is presented.
