报道了一种射频激励扩散型冷却千瓦 CO板条波导激光器。其上下两电极均采用液氮冷却 ,射频气体放电激励频率为 90 MHz,板条状波导增益区为 178mm(宽 )× 2 mm (高 )× 50 0 mm(长 )。气体是配比为 2 4 :71:4 :1的 CO、He、Xe、O2 混合气。所用的激光谐振腔由一个离轴虚焦非稳腔和一个平面后反馈镜构成。实验中 ,获得了 10 2 0瓦的 CO激光功率输出 A radio-frequency excited diffusion-cooled CO slab waveguide laser is reported. The upper and lower electrodes are all cooled by liquid nitrogen. The excitation frequency of radio frequency gas discharge is 90 MHz. The gain region of the slab waveguide is 178 mm (width) × 2 mm (height) × 500 mm (length). The gas is a mixture of CO, He, Xe, O2 with a ratio of 4: 71: 4: 1. The laser resonator used consists of an off-axis defocus chamber and a planar back-feedback mirror. In the experiment, a CO2 laser power output of 1020 watts was obtained
