进行了高电压轴向脉冲CO_2激光器的参量研究,参变量是管径、放电电压、放电电容及混合气。对于管径大于5厘米的激光器,单位放电长度的输出能量随管径线性地增加。以2.5厘米和5厘米直径的管子获得了容积比例尺。在2.5厘米直径的激光管中,总压力为90乇时获得4.8毫焦耳/厘米~3的最大能量密度。用15厘米直径的管子,长10米的激光器获得每个脉冲最大能量287焦耳,对于所有的激光器和气体条件,当施加电压增加时,输出能量增加,直至发生电弧放电。在最大的输出能量下,施加的电场对总气压之比近似为15伏/厘米·乇。最佳贮能电容随管径而增加。
The parameters of high-voltage axial pulsed CO 2 laser were studied. The parameters of variation were diameter, discharge voltage, discharge capacity and mixture. For lasers with a diameter greater than 5 cm, the output energy per unit discharge length increases linearly with tube diameter. Volumetric scales were obtained with tubes 2.5 cm and 5 cm in diameter. In a 2.5 cm diameter laser tube, a maximum energy density of 4.8 mJ / cm 3 was achieved at a total pressure of 90 torr. The maximum energy per pulse of 287 Joules was obtained with a 15 cm diameter tube and a 10 m long laser and the output energy was increased as the applied voltage increased for all laser and gas conditions until an arc discharge occurred. At the maximum output energy, the applied electric field to total pressure ratio is approximately 15 volts / cmTorr. The best storage capacitance increases with the tube diameter.
