This study presents a dissipative Talbot soliton fiber laser, demonstrating switchable breathing and stable dissipative Talbot solitons in a multicolor mode-locked fiber laser. The temporal Talbot effect governs the laser emission state, with the breathing state occurring when the integer self-imaging distance deviates from the cavity length and the steady state when it equals the cavity length. A refined Talbot theory incorporating dispersion and nonlinearity is proposed to accurately describe the evolution behavior of these solitons. The findings provide an effective way to control operation in dissipative optical systems and open new branches in nonlinear physics research. The Talbot effect, characterized by the replication of a periodic optical field, is extended to the temporal domain, where it enables the reconstruction of periodic pulse trains or the revival of pulse patterns with multiplied repetition rates. In mode-locked lasers, the Talbot effect is typically not linked with soliton dynamics due to the mismatch between longitudinal mode spacing and cavity dispersion. However, by manipulating the frequency difference of neighboring spectra, the study achieves switchable breathing and stable dissipative Talbot solitons in a multicolor mode-locked fiber laser. The study demonstrates that the temporal Talbot effect is dominant in the formation of dissipative Talbot solitons, with the laser operating in the breathing state when the integer self-imaging distance deviates from the cavity length and in the steady state when it equals the cavity length. The refined Talbot theory accounts for both dispersion and nonlinearity, providing a more accurate description of the soliton evolution. The results show that the dissipative Talbot soliton is formed in a laser system with dispersion, nonlinearity, gain, and loss, and that the self-imaging distance depends on both the dispersion value and pulse intensity. The study also shows that the dissipative Talbot soliton laser has unique synchronization properties and can generate a wide range of temporal behaviors, including ordinary and inverted breathing and stable dissipative Talbot solitons. The refined Talbot theory is validated through simulations and experiments, confirming its accuracy in describing the evolution of dissipative Talbot solitons. The results highlight the importance of the Talbot effect in nonlinear systems and open new avenues for research in nonlinear physics.This study presents a dissipative Talbot soliton fiber laser, demonstrating switchable breathing and stable dissipative Talbot solitons in a multicolor mode-locked fiber laser.
