  • Comparison of model predictions with experimental results.

    • Main Results:

    • The developed model accurately captures the dynamics of fiber laser arrays, including phase dynamics.
    • Results from the model show good agreement with existing experimental data.
    • The coupling strength in a 2-fiber interferometric array was found to have a negligible effect on the phase-locked state.

    Conclusions:

    • The new Maxwell-Bloch based model provides a more comprehensive approach to studying fiber laser array dynamics.
    • The findings suggest that phase-locking in certain interferometric fiber laser configurations is robust against variations in coupling strength.
