| 摘 要： | 本文应用瑞利-索末菲标量衍射理论分析了具有球面轮廓的折射微透镜对激光器输出高斯光束的准直特性.数值结果显示,在最佳准直条件下,高斯光束经过球面折射微透镜准直后的传输是一个振荡过程;同时,如果不考虑微透镜的衍射效率,当球面折射微透镜的F数越大,高斯光束经过准直变换后的远场发散角越小.

| Abstract: | The collimating properties of Gaussian beams by refractive microlens with sphericalprofile are analyzed with Rayleigh Sommerfeld scalar diffraction theory.The numerical results indicate that the microlens successfully collimate Gaussian beams,and that the propagation of Gaussian beams collimated by the refractive microlens with spherical profile is an oscillating process.If diffractive efficiency is not considered,the numerical results show that larger f number microlens has smaller divergence angle. |
