Complex variable function Gaussian beam in strongly nonlocal nonlinear media

TL;DR

This paper introduces a new class of Gaussian beams called CVF-Gaussian beams in strongly nonlocal nonlinear media, demonstrating their rotation, stability, and formation of solitons and breathers with various transverse profiles.

Contribution

It proposes the novel CVF-Gaussian beam model in SNNM and explores their dynamic behaviors, including rotation, stability, and soliton formation, based on input power control.

Findings

CVF-Gaussian beams can rotate during propagation in SNNM.

Stable CVF-Gaussian beams include rotating dipole and elliptic donut profiles.

The input power determines whether the beam forms a breather or a soliton.

Abstract

We introduce a novel class of spatial complex variable function Gaussian (CVF-Gaussian) beam, which is the product of an arbitrary analytic complex variable function and a Gaussian function, in strongly nonlocal nonlinear media (SNNM). The CVF-Gaussian beam rotates generally during propagation. By choosing the input power of the beam, we can obtain the CVF-Gaussian breather or the CVF-Gaussian soliton. We reveal that stable CVF-Gaussian beam can exist in SNNM with different forms, including rotating dipole, and rotating elliptic donut. A distribution factor which is the parameter for the description of the transverse distribution of the CVF-Gaussian beam is discussed.
