摘　　要：研制了用于抽运激光的分段表面放电辐射源。辐射源采用分段表面滑闪放电诱导长距离、线性等离子体通道大电流放电 ,实现了高亮度真空紫外辐射 (140～ 170nm) ,且各段总的放电分散时间小于 10 0ns。用该辐射源解离XeF2 获得了XeF (C A)An optical pump source is constructed on the basis of a sectioned low voltage surface discharge in the form of strictly linear plasma channels with a total working length of 42 cm and characterized by a small time scatter of operation (<100 ns) from the individual sections. The velocity of the dissociation wave and the brightness temperature of 15 kK in the spectral range 140-170 nm are calculated in terms of the streak photograph of the XeF(C-A) luminescence. Laser radiation on the C-A transitions from XeF pumped by this source is obtained.
