We investigate a superradiant lasing system with atom-atom interaction. We find that this interaction induces a squeezed lasing phase, demonstrating the importance of coherent many-body interactions in lasing.

Summary form only given. All the schemes of lasers without inversion (LWI) which so far have been realized experimentally involve external coherent field driving some auxiliary transition in three- or four-level atomic system. In this paper we prove that steady-state lasing without inversion via decay induced coherence in the closed four level atomic system is possible.
