Influence of amplification on pulse shaping for coherent control applications

Abstract
We demonstrate here the importance of using low seed laser powers for amplification of shaped pulses in a typical setup for coherent control experiments. An acousto-optic programmable dispersive filter (Dazzler from FastLite) is used to shape 130 fs pulses before amplification. These devices hold many advantages as compared to other pulse shaping devices [1]. Pulse shaping must be done with care in this configuration, as will be demonstrated with a number of examples of measured pulse shapes before and after amplification.
