Optimization of system parameters of a sealed-off CO_2 laser

摘要

Based on laser kinetics and diffraction theories of resonators, the gas mixtures (CO_2, N_2, He, Xe and H_2) and the resonator parameters of a typical sealed-off CO_2 laser are optimized by applying a genetic algorithm for obtaining a maximal laser output power. With the optimized parameters, the simulated and measured laser power is 2.27 and 1.6 times greater than the usually non-optimized CO_2 laser, respectively.
