简要地评述了在大气压强下工作的脉冲CO_2激光器电激励的问题,以及加拿大防御研究中心所研制的某些解决方法及其限制。根据一种双横向放电新技术,我们设计了一只3.8米长的激光器,输出为9焦耳/脉冲,峰值功率为12兆瓦。受激气体的输出能量密度已达到5.5毫焦耳/厘米~3。 A brief review of the electrical excitation of pulsed CO 2 lasers operating at atmospheric pressure and some of the solutions and limitations developed by the Defense Research Center of Canada are briefly reviewed. According to a new dual lateral discharge technology, we designed a 3.8-meter laser with an output of 9 joules per pulse and a peak power of 12 megawatts. The output energy density of the stimulated gas has reached 5.5 mJ / cm ~ 3.
