Abstract

The transition probabilities are calculated for 2-and 3-level atoms in an optically thick medium. The analysis is carried out in the frequency instead of the temporal domain. The response depends on whether the pulse shape is conserved when transformed into the momentum space. The propagation effects have been treated by McCall et al.¹ and by Konopnicki et al.² in the plane-wave regime and were extended to include diffraction.³
