Paper Abstract

In this research, the method of computer processing organic- glass burning-mark is used to measure the high power CO2 laser mode and space parameters (beam diameter, beam waist diameter, beam quality factor and divergence angle). The graphs of intensity distribution in cross-section of beam and its magnitude contours are given out. The results indicate that the output mode of some a import 5 kW transverse CO2 laser is non-symmetric Laguerre-Gauss beam which is mainly consisted of TEM02, TEM20 and TEM03, whose center region intensity is less than adjacency intensity, the size of the center bright spot is bigger, the distribution of power density is relatively uniform.
