Generalized phase synchronization in unidirectional coupled LD pumped Nd:YAG lasers

摘要

We experimentally investigate phase synchronization between two detuned response chaotic laser systems coupled to a slightly different drive oscillator. Our result is that phase synchronization can occur between response laser systems when they are electronically driven by correlated (but not identical) inputs from the drive oscillator. We call this phenomenon generalized phase synchronization and clarify its characteristics using temporal behaviors and phase portraits.
