Anomalous transverse transformation of astigmatic four-petal Gaussian beams in isotropic nonlocal nonlinear media
In this paper, the evolution dynamics of astigmatic four-petal Gaussian beams in isotropic nonlocal nonlinear media is investigated. A series of analytical expressions are derived to describe the beam evolution, the beam width, and the critical power. The anomalous transverse transformation is prese...
