%X The intensity distribution of fiber bundle coupling LD output beams is discussed.The optical field distribution of output end of fiber is analyzed based on the mode theory of the fiber transmit.The optical field distribution of output end of fiber is measured and numerically simulated,and the approximate expression is given.The intensity distribution of fiber bundle coupling LD output beams is numerically simulated and experimentally studied.The simulation results agreed well with the experimental ones.The results shows the intensity distribution of output end of fiber is a semi Gaussian distribute middle in Gaussian distribution and geometrical distribution.
