Photoelectron holography constitutes a powerful tool for the ultrafast imaging of matter, as it
combines high electron currents with subfemtosecond resolution, and gives information …

A comprehensive quantitative rescattering (QRS) theory for describing the production of high-
energy photoelectrons generated by intense laser pulses is presented. According to the …

We have studied the carrier-envelope phase-dependent above-threshold-ionization
processes by solving the time-dependent Schrödinger equation nonperturbatively. Our …

A theory describing above-threshold ionization of atoms and ions in a strong
electromagnetic field is presented. It is based on the widely known strong field …

A phase-controlled orthogonal two-color (OTC) femtosecond laser pulse is employed to
probe the time delay of photoelectron emission in the strong-field ionization of atoms. The …

We report an experimental and theoretical study of very low-energy photoelectrons in
tunneling ionization process from noble gas atoms interacting with ultrashort intense infrared …

Tunneling is often used to describe multiphoton ionization of rare gas atoms in infrared
fields. We test the tunneling approximation and its nonadiabatic extension by measuring the …

We have measured two-dimensional photoelectron momentum spectra of Ne, Ar, and Xe
generated by 800-nm, 100-fs laser pulses and succeeded in identifying the spectral ridge …

We analyze the two-dimensional momentum distribution of electrons ionized by few-cycle
laser pulses in the transition regime from multiphoton absorption to tunneling by solving the …
