Two-photon correlated<i>–</i>spontaneous-emission laser: Quantum noise quenching and squeezing

Abstract

Previous studies have shown that the possible utility of the two-photon laser as a squeezed-state generator is negated by spontaneous-emission fluctuations. We here show that a two-photon correlated--spontaneous-emission laser can produce light which is both squeezed and free from spontaneous-emission fluctuations.
