摘　　要：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A RF excited diffusively cooled carbon monoxide kilowatts laser is reported.In this laser,the top electrode was cooled with the tap water and the bottom electrode was cooled with the liquid nitrogen to maintain the slab waveguide gas discharge region at a low temperature.In the experiments,a slab waveguide region was excited by a RF transverse gas discharge at a frequency of90 MHz,a new type of optical resonator consisting of a con- ventional unstable resonator and a flat feedback mirror was employed. The maximum laser power output of over 1 kilowatts was obtained with a gas composition of P( CO) :P( He) :P( Xe) :P( O2 ) at a ratio of2 4:71 :4:1 .
