Whereas, long term interaction, which thermalizes the radiation field, can produce non-classical states of the radiation field only at sufficiently small temperatures. A measure of k-th order squeezing, stricter than the one proposed by Zhang et al, is used to check the emergence of squeezing. It is also shown that photons in the considered thermalized field would follow super-Poissonian statistics.

Starting with an introduction to the phenomena of EIT, we state the VUV problem and go on to describe the solution given by GS Agarwal and SP Tiwari (Ref[1]). With this, we note that one naturally arrives at the theoretical structure describing EIT. We conclude the report with mention of the first experimental realization of the phenomena of EIT (Ref[7]).

A brief theoretical description of the same has also been given. I have also discussed some of the theoretical aspects of ’Polarization Spectroscopy’, a class of Saturated Absorption spectroscopy. This is followed by a brief description
of the important instruments used in implementing the above mentioned spectroscopic schemes. With this background the results of the saturated absorption spectroscopy and polarization spectroscopy experiments with Rubidium (Rb) have been presented and their agreement with the theory has been pointed out. At the end of the report a variation of the above
schemes, proposed by my mentor, has been discussed and some of the corresponding experimental results have also been given.
