From: Full characterization of an attosecond pulse generated using an infrared driver
Spectra generated from Kr with sub-two-cycle pulses.
(a,b) The angularly resolved XUV spectrum where the wavefront rotation is parallel (a) to the slit and perpendicular (b) to the slit. The angularly resolved XUV signals from the left panels are plotted in the right panels as a function of the carrier-envelope phase of the driving laser pulse. (c) The drift of the spatial profile due to the time shift of the emitted attosecond pulse train. (d) The variation of the harmonic intensity with CEP originating from the selected fraction of the attosecond pulse train passing through the slit.
