abstract = "We present theoretical and computational investigations of the nonlinear dynamics and heterogeneity-promoted synchronization of diode laser arrays with decayed non-local coupling topology. The diode laser array exhibits a wide variety of dynamical behaviors as laser and coupling parameters vary. Here, we explore the dynamics for the intermediate and large coupling feedback strengths and further analyze the phase diagram and power spectrum as a function of the feedback strength, coupling topology, and misalignment introduced in the array. The dynamics induced by intermediate feedback are complex for small values of external cavity misalignment but display a clustering phenomenon consisting of several separate groups showing incoherent and coherent dynamics for the appropriate value of the cavity misalignment parameter. Furthermore, the dynamics and the power spectrum in the stronger feedback regime show frequency and phase-locking as the amount of misalignment disorder increases.",
