Abstract
The time-resolved cross-correlation measurements of extreme ultraviolet (xuv) pulses generated as high-order harmonic emission were analyzed. The ellipticity of laser driving the generation process was modulated such that polarization was linear for short times around temporal peak of pulse. The emission of xuv radiation was confined to times much shorter than laser pulse duration as harmonic generation was strongly suppressed for very small amounts of driving laser ellipticity. The results show that xuv pulse shortening represented plateau harmonics by temporally gating the driving laser ellipticity.
