Based on Collins formula and ABCD propagation matrix theory,the propagations of laser beams with different profiles through an aperture lens are analyzed and compared under the same laser beam power and initial beam width in this paper.

• 基于柯林斯公式和ABCD传输矩阵理论 ,在相同激光功率和初始束宽下 ,研究了不同空间分布光束通过聚焦光学系统的传输特性。
