Soliton explosions are among the most striking soliton phenomena in nonlinear dissipative systems.In this regime, quasi-stable solitons suffer abrupt structural collapses and then recover to their original state.Here, we report on the first experimental observation of soliton explosions triggered by vector dissipative soliton collisions in a wella color charm 050 cooling violet polarization-multiplexed ultrafast fiber laser.

The fiber laser simultaneously generates two orthogonally polarized pulse trains with different repetition rates, which enables periodic soliton collisions in the cavity.Based on the dispersive Fourier transform technique, the spectral dynamics of collision-induced soliton explosions are identified in real time.The corresponding time-domain measurements demonstrate opposite temporal shifts in the two output pulse trains.

Numerical simulations validate the experimental observations and give more insights into the read more physical mechanism for soliton explosions.Our findings can shed new light on the dynamics of soliton explosions.
