The paper reports the observation of switchable breathing and stable dissipative Talbot solitons in a multicolor mode-locked fiber laser by manipulating the frequency difference of neighboring spectra. The temporal Talbot effect, governed by dispersion and nonlinearity, dominates the laser emission state, with the laser operating in a breathing state when the integer self-imaging distance deviates from the cavity length and in a steady state when it equals the cavity length. A refined Talbot theory that includes dispersion and nonlinearity is proposed to accurately describe the evolution behavior of these dissipative Talbot solitons. This work opens new avenues for controlling dissipative optical systems and advancing the study of nonlinear physics.The paper reports the observation of switchable breathing and stable dissipative Talbot solitons in a multicolor mode-locked fiber laser by manipulating the frequency difference of neighboring spectra.
