Abstract

A sequence of two femtosecond coherent pulses—a strong π-polarized pulse and a weak σ-polarized pulse—excite the S1/2P1/2 transition of atomic rubidium in an optically dense vapor. The σ pulse induces transitions between the adiabatic states with a coupling strength that is different for identically and oppositely light-shifted coupled states, and that can be modified by tuning the relative phase between the pulses. An efficient control of the medium gain for the σ pulse is experimentally demonstrated. It is shown to be the result of interference between the absorption and the stimulated emission paths for σ photons.
