In the frame of the ADK theory, the tunneling ionization of an argon atom exposed to the light from Ti:Sapphire laser is investigated. We assume that the laser field is the radially polarized beam with donut. (0, 1)* Laguerre-Gaussian field distribut

Within the framework of the Ammosov–Delone–Krainov theory, we consider the angular and energy distribution of outgoing electrons due to ionization by a circularly polarized electromagnetic field. A correction of the ground ionization potential by

We discuss the effects of two different spatial and temporal laser beam profiles on the energy distribution of ionized photoelectrons. Two types of profiles of laser radiation, Gaussian and Lorentzian, are considered. The influence of the nonzero ini

In this paper we suggest that theories treating two interacting objects in a different manner (for instance electromagnetic field of a laser classically, and the interacting atom as a quantum object) should be called “mixed”. Mixed theories are n

Here, the method of including nonzero initial momenta for ejected electrons in strong infrared laser fields is further developed [8]. It has been shown that, apart from being natural, including the nonzero initial momenta enables one to go into a dee

Tunneling regime, introduced by Keldysh, in the interaction of strong lasers with atoms has been now accepted as the reliable method for describing processes when low frequency lasers are involved. Yet it was always assumed that the ionized electrons

Potassium atoms in circularly polarized laser field whose intensity (I) varies from 2 × 10 W/cm to 2.5 × 10 W/cm were studied. In the case when there is zero initial momentum, transition rate (that depends only on I) exhibits standard behaviour: as

The tunneling photoionization rate for a two color (bichromatic) field consisting of coherent superposition of the fundamental laser field frequency and its second harmonic with frequency 2, was studied theoretically within the framework of the adiab

In this paper, we use semiclassical model to discusse the kinetic electron energy distribution in the single tunnel ionization process of an atom with respect on the pulse duration and the spatial–temporal laser beam distribution. Our theoretical s

The two formulae for the energy at which the maximum number of ejected photoelectrons are detected are examined in this paper; one formula is Emax with non-zero momentum included in both the exponent and the pre-exponent part of the expression, and t
