Observation of the collision and oscillation dynamics of dissipative dual-color solitons.

Due to their potential as excellent dual-comb light sources, the dynamics of dual-color solitons within a single cavity have garnered widespread attention. In this work, we constructed a single-cavity ytterbium-doped passively mode-locked fiber laser (MLFL). By utilizing the birefringent filtering effect, dual-color solitons were successfully generated, and both collision and oscillatory dynamics of the dual-color solitons were observed.
