The study explores the impact of optical feedback on the dynamics of an external-cavity passively mode-locked surface-emitting laser, demonstrating that feedback acts as a solution selector that can either enhance or hinder the appearance of multistable harmonic arrangements of pulses. The theoretical analysis successfully replicates the experimental results and highlights asymmetrical resonance tongues caused by parity symmetry-breaking induced by gain depletion.
We analyze the effect of optical feedback on the dynamics of an external-cavity passively mode-locked surface-emitting laser operating in the regime of temporal localized structures. Depending on the ratio between the cavity round trip time and the feedback delay, we show experimentally that feedback acts as a solution selector that either reinforces or hinders the appearance of one of the multistable harmonic arrangements of pulses. Our theoretical analysis reproduces well the experiment and allows us to evidence asymmetrical resonance tongues due to the parity symmetry-breaking induced by gain depletion.
