| 摘 要： | 应用遗传算法,以输出激光功率为目标函数,优化确定了普通CO2激光器五种工作气体（CO2, N2, He, Xe, H2）的最佳充气量。对1.2m长谐振腔,在15kV放电条件下,优化的充气量分别为pCO2=1.15×133.3Pa, pN2=7.32×133.3Pa, pHe=12.95×133.3Pa, pXe=0.36×133.3Pa和pH2=0.01×133.3Pa。优化后激光功率比未优化前可提高1.27倍。

| Abstract: | 3Pa,p N2=7.32× 1 33.3Pa,p He=1 2 .95× 1 33.3Pa,p Xe=0 .36× 1 33.3Pa和 p H2=0 .0 1× 1 33.3Pa。优化后激光功率比未优化前可提高 1 .2 7倍Five gas components (CO2, N2, He, Xe and H2) in a CO2 laser are optimized by applying a genetic algorithm and taking the laser power as an objective function. With a resonator of 1.2m length and constant discharge voltage of 15kV, the laser power increases by 1.27 times after the optimization with the optimized gas pressures of 1.15×133.3Pa for CO22, 7.32×133.3Pa for N 2, 12.95×133.3Pa for He, 0.36×133.3Pa for Xe and 0.01×133.3Pa for H2 respeotively. |
