Abstract
In this paper, we present two methods for optimizing the process of high-harmonic generation. The first one consists in affecting the spectral phase of a driving laser using an acoustic-optical programmable dispersive filter called "Dazzler." By this method we have shown an enhancement of the efficiency and tuning of high-order harmonics. We also present a method for shaping the intensity distribution of an intense laser beam in the focal region by means of a bimorph adaptive mirror. First results on the control of harmonic spectra obtained with shaped intensity profiles are presented.
