Hyperfine spectroscopy using co-propagating pump-probe beams

Alok K. Singh, Sapam Ranjita Chanu, Dipankar Kaundilya +1

We have shown earlier that hyperfine spectroscopy in a vapor cell using co-propagating pump-probe beams has many advantages over the usual technique of saturated-absorption spectro…

Subnatural linewidth in a strongly-driven closed transition

Sapam Ranjita Chanu, Alok K. Singh, Boris Brun +2

We observe linewidths below the natural linewidth for a probe laser on a {\it two-level system}, when the same transition is driven by a strong control laser. We take advantage of…
