摘要: Synchronized dual-wavelength mode-locked laser is investigated numerically and experimentally in the normal dispersion regime. A programmable optical processor is introduced to shape the spectral profile and adjust the net dispersion, which is demonstrated be a convenient and reliable approach to generate dual-color solitons. The time-stretch dispersive Fourier transform and frequency-resolved optical grating techniques are utilized to measure the spectral and temporal characteristics of dual-color solitons, respectively. The numerical results are consistent with experimental results. This work may facilitate the development of filter-based mode-locked laser and the understanding of multi-wavelength soliton dynamics.
