“…T h e signal to noise ratio of the measured interferogram was 10: 1, which gives about 2% accuracy in the temporal reconstruction when the energy spectrum signal to noise is high (also 5O:l) [12]. It should be noted that the window function of the SPIDER algorithm significantly filters the noise [16].…”

“…In order to represent an ultrashort pulse in time and frequency domain, and to visualize the dispersion as well, we need to use Wigner function [25][26][27][28] . The latter function was originally introduced by Wigner to represent the quantum states in phase space 29 .…”

We investigated the effect of higher order dispersion on ultrafast photoionisation with Classical Trajectory Monte Carlo (CTMC) method for hydrogen and krypton atoms. In our calculations we used linearly polarised ultrashort 7 fs laser pulses, 6.5 × 1014 W/cm2 intensity, and a central wavelength of 800 nm. Our results show that electrons with the highest kinetic energies are obtained with transform limited (TL) pulses. The shaping of the pulses with negative second- third- or fourth- order dispersion results in higher ionisation yield and electron energies compared to pulses shaped with positive dispersion values. We have also investigated how the Carrier Envelope Phase (CEP) dependence of the ionisation is infuenced by dispersion. We calculated the left-right asymmetry as a function of energy and CEP for sodium atoms employing pulses of 4.5 fs, 800 nm central wavelength, and 4 × 1012 W/cm2 intensity. We found that the left-right asymmetry is more pronounced for pulses shaped with positive Group Delay Dispersion (GDD). It was also found that shaping a pulse with increasing amounts of GDD in absolute value blurs the CEP dependence, which is attributed to the increasing number of optical cycles.
