Abstract
Quantum wave packet engineering is demonstrated using a phase-programmable femtosecond optical source. This paper describes development of a programmable phase modulator and coherent control of quantum wave packets. Wave packet motion in a cyanine dye molecule is observed to be dependent on the chirp direction and rate of excitation pulses. Strong reduction in excited state population is efficient for negatively chirped pulses in the cyanine dye molecule, which is explained in terms of a pump-dump process. We discuss a possibility of mutual conversion between the optical and electronic phase information by means of nonlinear light-matter interaction.
