Abstract

In any laser fusion scheme dependent on adiabatic implosion of the fusion target, it is of the utmost importance to illuminate the target uniformly over its entire surface area. A convenient method of providing illumination over the entire spherical surface from two beams was proposed by Thomas.1 In this method, a catadioptric system is employed, involving a fast (NA 0.7) lens and a pair of ellipsoidal mirrors of eccentricity ⅓. Subsequent refinements of this scheme have been developed at the Lawrence Livermore Laboratory.2

双光束激光聚变实验照明系统设计
在任何依赖于靶材绝热内爆的激光聚变方案中,靶材整个表面的均匀照射都是至关重要的。thomas提出了一种从两束光束照射整个球面的简便方法。该方法采用反射系统,包括一个快速(NA 0.7)透镜和一对偏心率为1 / 3的椭球镜。劳伦斯利弗莫尔实验室对这一方案进行了进一步的改进
