分数薛定谔方程中燕尾高斯光束的可控反转与聚焦特性

Abstract: By transferring one-dimensional swallowtail catastrophe to optical field, the evolution dynamics of the swallowtail-Gaussian (SG) beams in fractional Schrödinger equation (FSE) with different potentials, where include the linear, parabolic and Gaussian potential and non-potential cases, are investigated by using the split-step Fourier method.
