From: Full characterization of an attosecond pulse generated using an infrared driver
Reconstructed spatial-temporal profile of an isolated attosecond pulse.
(a) Reconstructed XUV spectrum in the near-field where the XUV is generated. (b) The reconstructed spatial-temporal electron field of the attosecond pulse in near-field. The curves (white, green and yellow) correspond to the wavefronts for 40 eV, 50 eV and 60 eV photon energies. (c) The intensity profiles of the XUV emission in the near-field for y = 0 (blue) and y = 10.5 μm (red). (d) The intensity profiles of the XUV emission in the far-field for θ = 0 (blue) and θ = 0.8 mrad (red).
