LASER CONTROL OF POPULATION-DYNAMICS WITH BICHROMATIC FIELDS - DIRECTSEARCH THROUGH FIELD AMPLITUDE, FREQUENCY, AND PHASE-SPACE

A general technique for integrating through parameter space in order t o determine how the eigenvalues and eigenfunctions of the time-depende nt or time-independent Schrodinger equation change with parameter valu es is outlined, and its application to laser field amplitude, frequenc y, and phase (in a bichromatic field) are presented. The enhanced effi ciency of this method provides 3-D plots of the objective versus pairs of laser parameters (frequency and phase, amplitude and phase) thereb y permitting a visual determination of suitable field parameters which will help achieve desired populations in a multi-level system using a bichromatic field. Applications charting the field parameters for sel ective vibrational excitation of hydrogen fluoride are presented.
