摘要: It is theoretically shown how a two-photon laserlike oscillator with strongly squeezed output can be constructed. The physical mechanism leading to the strong competition among nonlinear gain due resonant four-wave mixing process, losses absorption of generated photons, and linear from cavity. In balanced case, photon correlations result in linewidth that narrower than Schawlow-Townes limit.
