Experimental Study on 100 J Level of Excimer Laser Pumped by REB
摘要
利用“闪光二号”相对论电子束加速器研制了百焦耳级XeCl和KrF准分子激光器，激光器激活体积24 l，输出口径20×20 cm2，泵浦功率密度1.5～2.0 MW/cm3。XeCl激光器最大能量136 J，波长308 nm，脉宽50～100 ns，峰值功率1.5 GW，采用虚共焦非稳腔技术，束散角达1.3 mrad；KrF激光最大能量157 J，波长248 nm，脉宽80～100 ns，峰值功率2 GW。
Abstract
A 100 J level of XeCl and KrF excimer lasers pumped by an intense relativstic electron beam (REB) accelarator Flash Ⅱ has been developed. The laser cell has an effective excitation volume of 24 liters and a 20×20 cm 2 aperture. The pump power density ranges between 1.5-2.0 MW/cm 3. The maximum output energy of 136 J with the pulsewidth of 50-100 ns and peak power of 1.5 GW is obtained for the XeCl (308 nm) laser. The divergence angle is 1.3 mrad by using the positive confocal unstable resonator technique. In KrF(248 nm) laser case, the maximum output energy is 157 J with pulsewidth of 80～100 ns and peak power of 2 GW.
