摘要
We report the"periodic"soliton explosions induced by intracavity soliton collisions in a dual-wavelength modelocked Yb-doped fiber laser.Owing to the different group velocities of the two wavelengths,the mode-locked solitons centered at different wavelengths would periodically collide with each other.By using the dispersive Fourier transformation technique,it was found that each collision would induce soliton explosions,but none of them would be identical.Therefore,this phenomenon was termed as"periodic"soliton explosions.In addition,the dissipative rogue waves were detected in the dual-wavelength mode-locked state.The experimental results would be fruitful to the communities interested in soliton dynamics and dual-comb lasers.
