FIELD-OPTIMIZED INITIAL STATE-BASED SELECTIVE CONTROL OF IBR PHOTODISSOCIATION

A new scheme for controlling photodissociation through preparation of a variationally optimized linear superposition of field-free vibration al eigenstates is applied for selective control of IBr photodissociati on. The dependence of IBr photodissociation on various field parameter s and initial conditions is explored. In a broad range of field parame ters, the product yield is shown to increase considerably when a photo lysis pulse is applied to the variationally optimized linear combinati on as opposed to photolysis of IBr with the entire population in a sin gle vibrational level. The frequency, intensity, and phase dependence of this enhancement is explored for both CW and Gaussian pulses.
