摘要：
To enhance lasing stability and improve laser processing qualities, we experimentally measure the transverse modes of a high power transverse-flow CO2 laser, analyzing mechanism of the laser transverse modes formed in the resonator. Further, we numerically simulate the lasing transverse distribution by solving the Maxwell equations for the configuration of tube-plate electrodes. It shows that the simulated lasing transverse modes come near the experimental observations. The peak values of lasing transverse modes are determined by both the electrode configuration and the flowing rate of the gas upon the given discharge voltage; while the transverse positions of laser peaks are determined by the flowing rate of gas.
