Manipulating Explosion Dynamics of Dissipative Soliton in an Ultrafast Fiber Laser with Dynamic Dispersion Engineering

Abstract

AbstractAs one of the most fascinating phenomena in dissipative systems, soliton explosions have been intensively investigated in the field of nonlinear optics owing to their intriguing dynamics. However, few efforts have been dedicated to precisely manipulating the dynamics of soliton explosion in fiber lasers. Herein, the exploding dynamics of dissipative soliton in a passively mode‐locked fiber laser by engineering the intracavity dispersion with a spectral pulse shaper is investigated. It is found that the exploding interval of the dissipative soliton can be well manipulated by dynamically engineering the cavity dispersion. The real‐time spectral dynamics of the soliton explosions are investigated by virtue of the dispersion Fourier transform (DFT) technique. The experimental results are further reproduced by the numerical simulations. These findings demonstrated that the dispersion engineering approach is a promising way to manipulate the soliton exploding behavior, and will also shed new light into the dynamics of soliton explosions in dissipative optical systems.
