对应的光源代入环形光路模型进行仿真模拟对应的光源代入环形光路模型进行仿真模拟，图为聚焦透镜前合束的环形光斑形态和能量分布的曲线图，不论是哪种光源，对应的环形光斑的外径变化几乎没有差异，但是光斑能量分布方式却大不相同，输入高斯型激光源形成的环形光束在聚焦前能量分布呈现变化连续的双峰状。而输入平顶型激光源所形成的光束在聚焦前能量向光环的内侧剧烈集中，由图b)可以看到峰值能量向外侧变化连续、向内侧出现了“骤降”。

The corresponding light source is substituted into the ring optical path model for simulation，the figure shows the shape of the annular spot and the energy distribution of the combined beam in front of the focusing lens, regardless of the source, there is almost no difference in the outer diameter of the corresponding annular spot, but the spot energy distribution is very different. In contrast, the beam formed by the input flat-top laser source has a sharp concentration of energy toward the inner side of the ring before focusing, as can be seen in Figure b), where the peak energy varies continuously toward the outer side and "plummets" toward the inner side.
