Abstract

The physics of high harmonics has led to the generation of attosecond pulses and to trains of attosecond pulses. Measurements that confirm the pulse duration are all performed in the far field. All pulse duration measurements tacitly assume that both the beam’s wavefront and intensity profile are independent of frequency. However, if one or both are frequency dependent, then the retrieved pulse duration depends on the location where the measurement is made. We measure that each harmonic is very close to a Gaussian, but we also find that both the intensity profile and the beam wavefront depend significantly on the harmonic order. Thus, our findings mean that the pulse duration will depend on where the pulse is observed. Measurement of spectrally resolved wavefronts along with temporal characterization at one single point in the beam would enable complete space-time reconstruction of attosecond pulses. Future attosecond science experiments need not be restricted to spatially averaged observables. Our approach paves the way to recovery of the single molecule response to the strong field.

(a) Experimentally reconstructed spectral wavefront phase and amplitude at the slit position for different harmonics. The harmonics H15 (data points plotted as ’x’) and H21 (data points plotted as '◇') are shown in red and blue respectively. The phase data points are interpolated by the dashed line, and the measured amplitude data points are shown interpolated by solid line. The background signal arises from stray light. (b) The difference between the fitted parabolic phase and the measured phase.

(a) Relative waist position (δZ) as a function of harmonic order. The error bar is shown within 95% confidence bounds. The insert illustrates that different harmonics “originate” from different positions in space. The meaning of the parameters δZ and Z13 is illustrated in the inset. (b) The beam waist size w0N as a function of harmonic order. The error bar is shown within 95% confidence bounds.

Fig. 3

Spatial-temporal coupling. Panel (e) shows the selected harmonics near their focal position assuming a focusing mirror of focal length f=100mm placed a the position of the scanning slit. We see that different harmonics focus at different positions and have different divergence. Panel (f) shows the Gouy phase of the same harmonics around the focus. Assuming transform limited pulse at the center of the focusing mirror (z = 0, R = 0 -panel (d)) we can determine the pulses temporal profile at any position. Panels (a), (b) and (c) show respective pulses at Z = 155mm, R = 0 (panel (a)); Z = 165mm, R = 0 (panel (b)) and Z = 0, R = 300μ (panel (c)). In (a)–(d) the field strength is normalized to unity. Red, green and blue colors show the results for 13, 19 and 23 harmonic respectively.
