Paper Abstract

Timed sequences of femtosecond pulses produced by pulse-shaping techniques have been used to achieve improved optical control over molecular motion in crystalline solids. Selected lattice vibrational modes in an organic molecular crystal have been driven repetitively by appropriately timed pulse sequences in a manner analogous to that in which a child on a swing is pushed repetitively with timed mechanical forces. Repetitive driving with a pulse sequence results in larger lattice vibrational amplitudes and improved modeselectivity compared to driving with a single pulse. Numerous applications of pulseshaping techniques in femtosecond spectroscopy are anticipated.
