激光直接驱动聚变中光束排布的优化
-
摘要: 为提高激光直接驱动聚变中球靶的辐照均匀性, 必须对光束的排布进行优化。 本文通过分析球谐模的几何因子, 提出了光束排布的优化规则。按照这个规则排布光束, 可在光束数有限的情况下获得较高的辐照均匀性。给出了满足此规则的一些典型光束排布实例。Abstract: In order to improve the irradiation uniformity of spherical target for laser direct driven sfsion, it is necessary optimizing the configuration of beams. By analyzing the geometrical factor of the spherical-harmonic modes, the general rules are proposed for optimizing the configuration of beams. According to the rules, one can obtain higher irradiation uniformity under the case of limited number of beams. Some typical examples that satisfy the rules are psented．
