| 摘 要： | 从广义惠更斯-菲涅耳衍射积分出发对厄米-余弦-高斯光束的传输特性作了研究，给出了厄米-余弦-高斯光束通过近轴ABCD光学系统的解析传输公式，以厄米-余弦-高斯光束通过自由空间和薄透镜系统为例做了数值计算和分析，结果表明厄米-余弦-高斯光束在自由空间传输时不能保持其形状不变。厄米-双曲余弦-高斯光束、余弦-高斯光束、厄米-高斯光束的传输公式可作为厄米-余弦-高斯光束的特例得出。

| Abstract: | Based on the generalized Huygens Fresnel diffraction integral, the closed form propagation expressions for Hermite cosine Gaussian(HCsG) beams through a paraxial optical ABCD system are derived. The propagation expressions for Hermite cosh Gaussian(HChG), cosine Gaussian(CsG) and Hermite Gaussian(HG) beams are obtained readily as special cases of HCsG beams. As application examples, numerical calculations are performed for HCsG beams propagating in free space and focused by a thin lens. The calculated results are shown that HCsG beams can not preserve their shape, while propagating in free space and through a thin lens. |
