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 first experimental observation of triggered by vector collisions a polarization-multiplexed ultrafast fiber laser. The laser simultaneously generates two orthogonally polarized pulse trains with different repetition rates, which enables periodic cavity. Based dispersive Fourier transform technique, spectral dynamics collision-induced identified real time. corresponding time-domain measurements demonstrate opposite temporal shifts output trains. Numerical simulations validate observations give more insights into physical mechanism for explosions. Our findings can shed new light
