  1. Abstract : the far - field spot characteristics of laser converted by random phase plate are analyzed theoretically, including the shape, size, rotational symmetry and diffractive efficiency of the spots, as well as the distribution of subsidiary spot. by comparing the influence of phase element shape ( triangular, square and hexagonal ) on the characteristics, we found that the random phase plate with hexagonal array structure is more suitable for the beam smoothing in laser fusion

    文摘:從理論上分析了激光經隨機位相板變換后在遠場的光特性(包括光的形狀、大小、旋轉對稱性、衍射效率以及旁瓣分佈) ,通過比較三種形狀位相元(等邊三角形、方形和六邊形)的遠場光特性,得知六邊形位相元的隨機位相板更適合於激光聚變中的束勻化。
