This paper reports the first experimental measurements of atomic hydrogen ionization using few-cycle laser pulses, demonstrating good agreement with theoretical simulations across various intensities and energies.

Contribution

It provides the first experimental data on hydrogen ionization with few-cycle pulses and validates ab initio simulations against the measurements.

Findings

Quantitative agreement between experiment and theory at 10% level.

First experimental data on hydrogen ionization with few-cycle pulses.

Broad range of laser intensities and electron energies studied.

Abstract

We present the first experimental data on strong-field ionization of atomic hydrogen by few-cycle laser pulses. We obtain quantitative agreement at the 10% level between the data and an {\it ab initio} simulation over a wide range of laser intensities and electron energies.
