横向双放电激励高气压CO_2激光器,在0.9升的放电体积中实现了每秒一次重复率的均匀激励。在大气压时激光输出能量最大可达18焦耳/脉冲,脉冲功率估计为30兆瓦,效率约12.3％。工作着重于获得均匀放电,以提高输入及输出的能量密度。还分析和讨论了工作气体的成分和压力对激光器性能的影响。 The lateral double-discharge excited high pressure CO 2 laser achieves a uniform excitation at a repetition rate of once per second in a discharge volume of 0.9 liters. At atmospheric pressure laser output energy up to 18 joules / pulse, the pulse power is estimated at 30 MW, the efficiency of about 12.3%. Work focuses on achieving uniform discharge to increase the energy density of the inputs and outputs. The effects of working gas composition and pressure on laser performance were also analyzed and discussed.
