✦ Synopsis

Three pressures of gases (CO2; N2 and He) added into CO2 laser tube are optimized for obtaining maximal laser output power by applying a genetic algorithm and solving the CO2 laser kinetics equations. After the optimization, the laser power is increased by 96% as compared with a non-optimal case.

For a high-power CO 2 laser with a close-confined structure, the compositions and ratios of gas mixtures are changed due to electron impacts during the laser-operating period. As a result, the laser performance is gradually degraded, even to non-lasing output. In this paper, three different methods
