Abstract

ABSTRACT We have considered general polarization-sensitive correlation measurement of light intensity fluctuations basedon Hanbury Brown and Twiss interference detection scheme for probe radiation passed through angular momentum polarized atomic ensemble put into external magnetic field. The general theory is applied to the correlationspectroscopy of the atomic medium with spin ground state characterized by large relaxation times. We showand discuss the possibility of squeezing effect in transmitted light that can be caused by polarization-dependentinteraction of the probe radiation with oriented atoms. 1.INTRODUCTION Since the first experiment of Hanbury Brown and wiss' the statistical and coherence properties of lighthave attracted considerable attention of researchers in both fields of experimental and theoretical physics. Themeasurements of second and higher order intensity correlation functions can provide new information aboutlight itself and about medium monitored by light. The information obtained from correlation measurementshas been widely used in different applications. Many examples of squeezing phenomena have demonstrated
