Levy statistical fluctuations from a Random Amplifying Medium
Divya Sharma, Hema Ramachandran, N. Kumar
We report the studies of emission from a novel random amplifying medium that we term a ``Levy Laser'' due to the non-Gaussian statistical nature of its emission over the ensemble o…

Fluorescence from doubly driven four-level atoms - A density matrix approach
Andal Narayanan, R. Srinivasan, Ashok Vudayagiri +2
The unusually narrow features in the fluorescence from Rubidium-85 driven by cooling and repumper laser fields, reported in an earlier experiment [1] are explained on the basis of…

The backscattering of polarised light from turbid media - An analysis of the azimuthal intensity variations and its implications for the position of the source of diffusing radiation
Venkatesh Gopal, Hema Ramachandran, A. K. Sood
We study the azimuthal variation in the backscattered intensity that is seen when polarised light is scattered by a turbid medium. We present experimental observations of these int…
