Abstract
In a three-level CS2 system coupled with two pulsed photon fields, we have observed stimulated emission at a time when the stimulating photo n pulse precedes the pump photon pulse by 2.5 pulse widths. This count erintuitive time sequence in photon-matter interaction was interpreted by a model as emission resulting from photon dressed transient states (superposition of molecular quantum states in a Schrodinger equation approach) evolution. The model calculation is also able to simulate th e observed quantum interference between two populated levels.
