摘要: In this paper we investigate the effect of two incoherent steps on the statistical properties of cascade lasers without and with inversion. It is demonstrated that the noise in the intensity difference may be reduced 50% below the shot noise. A simple physical explanation of the mechanism for squeezing is given.
