Abstract
In this paper, the properties of four-petal Lorentz–Gaussian beams (FPLGBs) during propagation in the strongly nonlinear nonlocal media (SNNM) are investigated by using the Collins formula. The impact of the beam and media parameters on the propagation of an FPLGB is investigated analytically. The intensity distribution of an FPLGB during propagation in the SNNM evolves periodically and the initial beam profile with four beamlets disappears for enormous values of the input power.
期刊介绍：
This journal is devoted to the rapidly advancing research and development in the field of nonlinear interactions of light with matter. Topics of interest include, but are not limited to, nonlinear optical materials, metamaterials and plasmonics, nano-photonic structures, stimulated scatterings, harmonic generations, wave mixing, real time holography, guided waves and solitons, bistabilities, instabilities and nonlinear dynamics, and their applications in laser and coherent lightwave amplification, guiding, switching, modulation, communication and information processing. Original papers, comprehensive reviews and rapid communications reporting original theories and observations are sought for in these and related areas. This journal will also publish proceedings of important international meetings and workshops. It is intended for graduate students, scientists and researchers in academic, industrial and government research institutions.
