Dual-wavelength mode-locked honda weathershields fiber lasers have attracted great attention due to their enormous potential in facilitating dual-comb spectroscopy.However, mechanism for dual-wavelength dissipative soliton mode-locking and the intracavity dynamics are still elusive.In this paper, we construct a simple and universal model to numerically investigate the intracavity buildup dynamics of dual-wavelength mode-locking in an all-normal dispersion fiber laser.

By resolving the pulses evolution and their interactions, we find that the chromatic dispersion induced pulse collision plays an important role in dual-wavelength pulses formation and propagation.At the chaotic stage, the collision-induced energy upheaval results in drastic nonlinear coupling effects, which contribute to the dual-wavelength mode-locking and formation of dual-wavelength soliton molecules.While at the stable dual-wavelength mode-locking stage, the two asynchronous pulses periodically collide, accompanying extremely intense wave generation and spectral explosion.

Moreover, cavity energy and gain competition iphone 12 price florida are modeled and optimized to realize the self-started pulse-splitting-free dual-wavelength mode-locking.
