高斯光束通过负圆锥棱镜光学系统的传输特性

Propagation of Gaussian beam through a negative axicon and its propagation properties

负圆锥棱镜的锥角小于5°的情况下可视作一个失调系统,运用该失调系统的4×4阶增广矩阵和失调系统的衍射积分公式分析了高斯光束通过负圆锥棱镜的传输特性,得到了出射光场的解析表达式,用计算机数值计算方法研究了光强分布规律。

The negative axicon was regarded as a misaligned system at the condition of the cone angle 〈 5° and the 4×4 augmented matrix of the rnisaligned system has been gotten, Propagation properties of Gaussian beams through a negative axicon were studied by using the misaligned diffraction integral. The intensity distribution for Gaussian beam propagating through a negative axicon was studied by numerical calculation.
