The vertical excitation axial flux kilowatt CO 2 laser is an equipment widely used in the high power laser heat treatment industrial applications. The experimental measurements indicate that the power density distribution of laser beam is generally of ring distribution with a sunken at the center, therefore the laser beam cannot be simply regarded as base mode Gaussian beam. In this paper, such laser beam is regarded as the non interference superposition of TEM 00 and TEM 01 mode beams, the method to determine the simulation parameters is discussed, and the relevant heat effect calculation equation is deduced.
