Abstract
This work finds its place in the statistical mechanical approach to light amplification in disordered media, namely Random Lasers (RLs). The problem of going beyond the standard mean-field Replica Symmetry Breaking (RSB) theory employed to find the solution of spin-glass models for RLs is addressed, improving the theory towards a more realistic description of these optical systems. The leading model of the glassy lasing transition is considered: the Mode-Locked (ML) 4 phasor model. This is a complex spherical 4-spin model, with a deterministic selection rule, affecting the coupling of the electromagnetic field modes. The model is investigated with both numerical and analytical techniques.
