Figure 1
(a) Photoelectron spectra lying towards the high-energy side of the He 1 s−1 photoelectron line plotted with respect to the shot number. The photon energy was 40.8 eV. The NIR field intensity was 6.0 × 1010 W cm−2. The background pressure of the vacuum chamber was ∼1 × 10−9 Torr, and the pressure was ∼1 × 10−8 Torr when the He gas was introduced to the chamber. A retarding voltage of −15 V was applied to decelerate the photoelectrons. (b) Averaged photoelectron spectra sorted into 10 fs time bins. SB1 in the figure denotes the first sideband peak. (c) Red circles: the temporal profile of the SB1 intensity. Blue line: Gaussian fit to the experimental data points (red circles) of the temporal profile.
