| 中文摘要 | based on the huygens-fresnel diffraction integral, analytical representation of unapertured converging hermite-cosh-gaussian beams is derived. focal switch of hermite-cosh-gaussian beams is studied detailedly with numerical calculation examples and a physical interpretation of focal switch is presented. it is found that decentered parameter is the dominant factor for the emergence of focal switch, and fresnel number affects the amplitude of focal switch and the value of critical decentered parameter to determine emergence of focal switch. physically, the emergence of focal switch of hermite-cosh-gaussian beams is resulted from competition between two major maximum intensities and switch of the absolute maximum intensity from a point to another when decentered parameter increases.
