摘要：
For obtaining the maximal output power, five lasing gas mixtures (CO2, N-2, He, Xe and H-2) in a sealed-off CO2 laser are optimized by applying a genetic algorithm and solving CO2 laser kinetics equations. A comparison of numerical simulations shows that the optimal pressures of CO2 and N-2 are 1.15 Torr and 7.32 Torr, respectively. Accordingly, the maximum laser power of 124 W is obtained by utilizing the optimal gas combination and an optimized resonator with a length of 1.2 m.
