✦ Synopsis

A method for calculation the mode contents of high-power CO blending-mode laser beam is presented. The basic idea is 2 based on the changing rule of transverse intensity distribution of blending-mode laser beam. Based on two arbitrary measured transverse intensity distributions, the beam's mode contents and phase shifts of blending-mode laser beams are calculated by means of the least squares method and iterative process. Moreover, through the calculation results, any transverse intensity distribution for blending-mode laser beam is simulated and beam quality is also calculated readily.
