“…These can be derived from a widely accepted model of laser tunnel ionization [11]. However, here we will make use of the fact that the nascent momentum distribution can be measured directly [12,13].…”

Precise in-situ measurement of laser pulse intensity using strong field ionization Smeenk, C.; Salvail, J. Z.; Arissian, L.; Corkum, P. B.; Hebeisen, C. T.; Staudte, A.Precise in-situ measurement of laser pulse intensity using strong field ionization (2004)], we devise an improved method for an in-situ measurement of the peak intensity in a focused, femtosecond infrared laser pulse. The method is shown to be effective with both photoion and photoelectron imaging devices. The model used to fit the experimental data has no unphysical free parameters used in fitting. The accuracy of the fit is 4% and the overall accuracy of the measurement is 8%.

“…8 However, despite the high cost of these cameras, the time resolution is still not sufficient to slice electrons. Baumert and co-workers 12 and Corkum and co-workers 13 developed tomographic reconstruction methods of 3D electron distributions by taking 2D images at many different polarization angles with respect to the detector. The procedure for such reconstruction methods is lengthy and the demonstrated energy resolution was limited.…”

We develop a new method to achieve slice electron imaging using a conventional velocity map imaging apparatus with two additional components: a fast frame complementary metal-oxide semiconductor camera and a high-speed digitizer. The setup was previously shown to be capable of 3D detection and coincidence measurements of ions. Here, we show that when this method is applied to electron imaging, a time slice of 32 ps and a spatial slice of less than 1 mm thick can be achieved. Each slice directly extracts 3D velocity distributions of electrons and provides electron velocity distributions that are impossible or difficult to obtain with a standard 2D imaging electron detector. © 2014 AIP Publishing LLC.

“…Basic control of the ellipticity of the pulse was achieved via a λ=4 plate, while more complex pulse shapes were attained with the use of a spatial light modulator in a 4f configuration [22,26]. In the case of cylindrically symmetric distributions, a single 2D projection is sufficient to reconstruct the full 3D distribution via standard inversion techniques [27]; for noncylindrically symmetric distributions, several projections must be obtained and a tomographic reconstruction technique applied to obtain the original 3D distribution [24,28,29].…”

Ionization occurs by a net three-photon absorption process, driven via the 4s → 4p resonance at the one-photon level. A theoretical treatment incorporating the intrapulse electronic dynamics allows for a full set of ionization matrix elements to be extracted from 2D imaging data. 3D PADs generated from the extracted matrix elements are also compared to experimental, tomographically reconstructed, 3D photoelectron distributions, providing a sensitive test of their validity. Finally, application of the determined matrix elements to ionization via more complex, polarization-shaped, pulses is demonstrated, illustrating the utility of this methodology towards detailed understanding of complex ionization control schemes and suggesting the utility of such "multiplexed" intrapulse processes as powerful tools...
