摘要
本文使用稳相法对无衍射光束的传输特性作了详细的理论分析，并与高斯光束作了比较。选用轴棱镜产生近似零阶贝塞尔光来的方案，进行有关零阶见塞尔光束传输特性的实验研究，取得了在误差范围内实验与理论计算一致的结果。
In this paper, by using the stationary-phase method the propagation properties of diffraction-free beams are analyzed in detail and compared with those of Gaussian beams. An axicon i3 used tOproduce the zeroth-order Bessel beam and then its propagation properties are studied experimentally. Theresults are consistent with the theoretical prediction.
