Figure 1: Schematic illustration of multidimensional control over the properties of attosecond pulses. The two control axes are two independent parameters of the fundamental field, for example, the relative delay and intensity of two harmonics that compose the field. The target is a chosen property of the attosecond pulse. Three optimization schemes are illustrated, in which the optimized target is (from left to right) the duration, cutoff frequency, or photon flux.
