研究了微波放电激励CO/sub 2/激光器。采用2.45GHz谐振腔实现了高功率激光运转。利用轴向快速气流、轴向电场和轴向激光束组成的系统进行了激光实验。在TM/sub 010/-模腔两端板上装有凹腔型调谐器，获得了均匀放电。用SUPERFISH程序计算了充有介质管的圆柱形空腔内的电场，并与测量结果进行了比较。采用新研制的双腔CO/sub 2/激光器模块，获得了259 W的激光输出和14%的效率（射频功率与激光功率的转换比）。>
Microwave discharges for excitation of CO/sub 2/ lasers have been investigated. A resonant microwave cavity (2.45 GHz) has been employed to get high power laser operation. Laser experiments using a system composed of axial fast gas flow, axial electric field, and axial laser beam have been performed. Homogeneous discharges have been obtained by a TM/sub 010/-mode cavity with reentrant type tuners on the both end plates. Calculations of the electric field inside the cylindrical cavity filled with a dielectric tube using the program SUPERFISH were compared with the results of the measurements. The laser output of 259 W and the efficiency of 14% (rf power to laser power conversion ratio) were obtained from a newly developed two-cavity CO/sub 2/ laser module. >
