.Propagation of hermite-cosh-gaussian beams passing through ABCD optical system with an annular aperture[J].Optoelectronics Letters,2008,4(1):78-80 Propagation of hermite-cosh-gaussian beams passing through ABCD optical system with an annular aperture TANG Bin JIANG Xing-fang LIU Zhi-min [1]School of Mathematics ＆ Physics, Jiangsu Polytechnic University, Changzhou 213016, China [2]School of Natural Science, East China Jiaotong University, Nanchang 330013, China Abstract:       By using the expansion of the aperture function into a finte sum of complex Gaussian functions, the corresponding analytical expressions of Hermite-cosh-Gaussian beams passing through annular apertured paraxially and symmetrically optical systems written in terms of ABCD matrix were derived, and they could reduce to the cases with squared aperture. In a similar way, the corresponding analytical expressions of cosh-Gaussian beams through annular apertured ABCD matrix were also given. The method could save more calculation time than that by using the diffraction integral formula directly. Hits: 3734 Download times: 214 View Full Text    Download reader
