Quantum Theory of the Steady-State Sub-Poissonian Laser Light without Inversion from Conventionally Pumped Lasers
We discuss the steady-state and quantum noise behaviors of coherently or incoherently pumped conventional three-level lasers. It shows that the sub-poissonian statistics can be predicted in the regime where pumping rates can be comparable with the spontaneous rate of lower lasing level and lasing is not optimal. But only for coherently pumped case, lasing without inversion can occur and noise squeezing is increased because of quantum-interference effect.
