Observation of linewidth of electromagnetically induced transparency with temperature

Abstract

The EIT linewidth plays an important role in high-precision spectroscopy. The EIT linewidth depends on the parameters like laser intensity, doppler broadening and atomic relaxation, etc. In this study, we have observed the dependence of EIT linewidth on the temperature in the D2 transition of 87Rb. The optical density increases with the increase of temperature, which has application in light storage [1], [2].
