Effect of biased noise fluctuations on the output radiation of coherent beat laser

TL;DR

This paper investigates how biased noise fluctuations influence the squeezing and intensity of radiation in a coherent beat laser, revealing conditions that enhance squeezing outside and inside the cavity.

Contribution

It demonstrates the impact of biased noise input on squeezing and shows how external environment modes affect the radiation properties depending on initial atomic states.

Findings

Squeezing occurs both inside and outside the cavity under certain conditions.

Biased noise input significantly enhances the degree of squeezing.

Radiation intensity outside the cavity remains lower than inside, regardless of parameters.

Abstract

Effect of biased noise fluctuations on the degree of squeezing as well as the intensity of a radiation generated by a one-photon coherent beat laser is presented. It turns out that the radiation exhibits squeezing inside and outside the cavity under certain conditions. The degree of squeezing is enhanced by the biased noise input significantly in both regions. Despite the presence of the biased environment modes outside the cavity, the degree of squeezing outside the cavity can be greater than or equal to or even less than the cavity radiation depending on the initial preparation of the atomic superposition and amplitude of the external driving radiation. But the intensity of the radiation is found to be lesser outside the cavity regardless of these parameters.
