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斑特性（包括光斑的形狀、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、正方形和正六邊形）的遠場光斑特性，得知正六邊形位相元結構的隨機位相板更適合於激光聚變中的束勻化。 -
A construction mystery of snowflakes is the average hexagonal shape, which may contain as many as 100 million or more water molecules. in certain conditions, the growing process proceeds in both perfectly horizontal and perpendicular directions, thus building a broader and thicker crystal in hexagonal symmetry
