RESONANCE FLUORESCENCE OF A 3-LEVEL ATOM DRIVEN BY DELAYED LASER-PULSES

A study of the resonance fluorescence emitted by a three-level atom dr iven by delayed laser pulses is presented with the main aim of investi gating the effect of the pulse order on the fluorescence spectrum. The use of a short-pulse approximation, introducing a significant simplif ication in the problem, allows one to provide an explicit expression f or the spectrum. Analytical results, obtained in the framework of the adiabatic interaction, are presented and compared with numerical calcu lations. As an example, an analytically solvable particular case is al so presented. (C) 1998 Elsevier Science B.V.
