Abstract

Control of population inversion and coherence generation between the ground and excited states in Hydrogen–like alkali atoms is presented in this work using multiphoton π-pulse scheme with pulse durations between 100 fs to 10 ps. Density matrix (DM) equations of 4–level Rb and Cs systems are numerically solved beyond the rotating wave approximation (RWA) taking detuning and spectral chirp into account. An extension of the study is done to nP_3/2 (n = 12) and nF_5/2 (n = 8) of Cs atoms demonstrating the applicability of the current scheme in selective Rydberg excitation and potential extendibility to numerous configurations.
