This talk will describe the general features of coherent control with shaped, broadband, femtosecond pulses. Recent work in our laboratory has focussed on coherent population transfer and CARS spectroscopy using shaped tuneable femtosecond pulses. The talk by Valery Milner in this session will describe the coherent population transfer experiments, while this talk will focus on using broadband femtosecond pulses for high resolution CARS spectroscopy. In recent publications, we have described the use of shaped broadband pulses to completely characterize, with high energy resolution, molecular vibrations(1), and the use of noise auto-correlation to record a high resolution CARS spectrum(2). Extensions of this work into coherent control of CARS intensities and all-optical processing of femtosecond CARS to produce a high resolution spectrum will be used to illustrate the power of femtosecond CARS.
