We investigate phase locking of large arrays of coupled lasers in a modified degenerate cavity. We show that the minimal loss lasing solution is mapped onto the ground state of an XY spin Hamiltonian when all the laser intensities are uniform. We study the probability to obtain this ground state for various coupling schemes, system parameters and topological constrains. We demonstrate the effects of quenched disorder, Crowd Synchrony, Artificial Gauge Fields and non-Hermitian Physics. Finally, we use our system to solve related problems such as phase retrieval, imaging through scattering medium, many-body mode interactions, and more.
