摘要
应用旋转棱镜和组合光学系统能够将高斯光束变换成“无衍射”贝塞尔（Ｂｅｓｓｅｌ）光束，并能实现实心和环状光束的相互变换。本文对旋转棱镜及其组合系统的成像特征作了详细理论分析和实验研究，得到二者相一致的结果，证实了该光学系统在激光技术中有广泛的应用前景。
Using axicon-based optical devices can realize such transormations as Gauss'beam into a diffraction-free Bessel beam,solid beam and annular beam converting eachother.In this paper,the combining optical systems are analyzed theoretically and studiedexperimentally in detail,both of the results are in agreement.It is shown that the axiconbeam converters have wide applications in laser techniques.
