摘要

Using the split-step Fourier transform method,we numerically investigate the generation of breathing solitons in the propagation and interactions of Airy-Gaussian (AiG) beams in a cubic-quintic nonlinear medium in one transverse dimension.We show that the propagation of single AiG beams can generate stable breathing solitons that do not accelerate within a certain initial power range.The propagation direction of these breathing solitons can be controlled by introducing a launch angle to the incident AiG beams.When two AiG beams accelerated in opposite directions interact with each other,different breathing solitons and soliton pairs are observed by adjusting the phase shift,the beam interval,the amplitudes,and the light field distribution of the initial AiG beams.
