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 presen
We have calculated the propagation dynamics of an initial off-axis vortex with topological charge 1 in Laguerre-Gaussian background beams ðLG 0 1 and LG 0 7 Þ, which are examples of background beams with non-generic dislocation surfaces, on which the real and imaginary parts of the light field are z
