在已设计的 16阶用于将He Ne基模高斯光束转换为厚环形光束二元光学元件基础上 ,模拟计算了输入光束光斑半径变化对所设计的二元光学元件整形环效果的影响 ,模拟结果显示 ,当光斑半径偏离设计值在± 5 0 μm范围内 ,环上均匀性的均方误差不超出设计值的 5 %。同时 ,给出了输入光斑半径为 1.74 5mm时的实验结果及6 6 0nm半导体激光实验结果 Based on the 16th order designed for transforming He Ne fundamental Gaussian beam into a thick annular beam binary optical element, the effect of input beam spot radius variation on the shaping ring effect of the designed binary optical element is simulated and simulated The results show that the mean square error of the ring uniformity does not exceed 5% of the designed value when the spot radius deviates from the design value within ± 50 μm. At the same time, the experimental results when the input spot radius is 1.74 mm and the experimental result of 6 6 0 nm semiconductor laser are given
