摘要
描述了脉宽１００ｎｓ强流脉冲电子束单向泵浦百焦耳级ＫｒＦ准分子激光用大面积二极管的实验研究。采用１２ｃｍ×７５ｃｍ长方形碳毡阴极，３０μｍ厚铝膜或九根间距１３ｍｍ，直径１．３ｍｍ的金属丝组成的阳极。当阴阳极间距为２０～２２ｍｍ，Ｍａｒｘ发生器电压１．１～１．２ＭＶ时，二极管峰值电压为６２０～６７０ｋＶ，峰值电流１５０～１７０ｋＡ，电子束总能量大于８ＫＪ，使电子束泵浦ＫｒＦ激光器最大输出能量达１０６Ｊ。
Experimental investigation is described of a large area diode for a hundred-joulelevel KrF excimer laser pumped by an intense pulsed electron beam of 100ns.Using a 12cm × 75cmrectangular carbon felt cathode an anode of 30μm Al foil or 9 wires of Φ1.3mm spaced by 13mmfrom each other,the total electron beam energy of high than 8kJ is obtained at the electrodeseparation of 20～22mm,Marx generator voltage of 1.1～1.2MV_s diode peak voltage of 620～670kVand diode peak current of 150～170kA。The maximum output energy of 106J is achieved for theKrF laser beam.
