Synchronization of chaotic oscillations between external-cavity and injected semiconductor lasers is experimentally observed in a low-frequency fluctuation regime. Not only from the occurrence of power drop events between their waveforms but also from the detailed structures of mode transition in power recovery processes of low-frequency fluctuations, it is confirmed that the two systems are synchronized in coherence-collapse states.
