大口径铜蒸气激光器的动力学分析

KINETIC ANALYSIS OF LARGE-BORE COPPER-VAPOR LASER

通过建立调整大口径铜蒸气激光器的动力学模拟过程中的有关动力学参数,得到一适用于不同输出功率的大口径铜蒸气激光器动力学模型.在此基础上对大口径铜蒸气激光器的径向动力学参量进行了计算,包括激励电场和亚稳态铜粒子密度等动力学参量的径向分布.给出了大口径铜蒸气激光器的径向电子温度及发光强度分布.尔后得到在不同充电电压及缓冲气压条件下铜蒸气激光器的输出功率,此程序对Φ=65cm的大口径铜蒸气激光器的计算结果与实验符合得相当好.

Through establishing and adjusting the kinetic parameters, a kinetic model for a series of large\|bore copper\|vapor lasers is completed. On the basis of this model the radius kinetic parameters are calculated, including the stimulating electric field and the metastable state copper density. The radial electron temperature and intensity of large\|bore copper laser are presented. Then the output power under different buffer gas pressurs and charging voltages are given. These are in good agreement with the calculated and measured results for Φ =6\^5?cm copper vapor laser.
