SIMULTANEOUS CONTROL OF SELECTIVITY AND YIELD OF MOLECULAR DISSOCIATION - PULSED INCOHERENT INTERFERENCE CONTROL

The theory of resonantly enhanced molecular dissociation induced by a two-pulse sequence to a continuum which is dressed by a third pulse is developed. Closed form expressions for the state preparation and evol ution are derived within the adiabatic approximation. Non-approximate numerical calculations demonstrate that extensive branching ratio cont rol and high dissociation yield (near 100 percent) are simultaneously achieved by varying the central frequencies of one pulse relative to a nother. The control characteristics are found to depend strongly on th e ordering of the three-pulse sequence. (C) 1997 Elsevier Science B.V.
