“…With the trajectory (14) the integral in (18) can be evaluated analytically by omitting terms of the order of 1/γ and keeping only a part of Coulomb-induced contributions linear with respect to the small parameter μ. After substitution of the integration result into (18) the matching point ξ * = ξ(τ * ) entirely cancels, which justifies consistency of the matching procedure.…”

“…It is worth noting that pulsed field ionization of atoms for both d.c. and microwave cases has been well studied in the past. 13 For example, in the microwave region (where photon energies are of order 10 eV) a discuulon of photon and field descriptions has been presented as It relates to ionization rate limits in alkali atoms. In the referenced microwave caaes atoms were initially excited to high Rydberg levels because the field amplitudes were orders of magnitude lower than those now achievable for the visible frequencies.…”

The ultra•fast ionization of argon, krypton and xenon by intense ultra-short laser pulses is studied. Intensities in the range 1014 to 1016 W/cm2 at a wavelength of 616 nm &e provided by a colliding pulse mode-locked dye laser system. To date, ion yields have been monitored using a 1 meter time.offlight spectrometer. Intensity dependent photoelectron signals are deduced from ion data. In an ultra-fast strong field environment, ionization times can be less than an optical period, affording a better distinction between a field ionization picture and a multiphoton ionization picture. For most cases that we study, Keldysh parameters are below 1, indicating that we are in a field ionization regime. As a laser system under development progresses towards the design goal of 1 joule per 100 femtosecond pulse, we will extend these investigations to peak intensities of order 1018 to 1019 Watts/cmZ.

“…Usually, this correction increases the tunnel ion ization probability by several orders of magnitude (this effect was reliably established in experiments; see, for example, [24]). At present, the expressions for tunnel ionization rate taking into account the Coulomb cor rection (and also known as the Ammosov-DeloneKrainov formulas [25]; see [26]) are widely used for calibrating the laser pulse intensity.…”

Abstract-Coulomb corrections to the action function and rate of multiphoton ionization of atoms and ions in a strong linearly polarized electromagnetic field are calculated for high values of the Keldysh adiabaticity parameter. The Coulomb corrections significantly increase the ionization rate for atoms (by several orders of magnitude). An interpolation formula proposed for ionization rate is valid for arbitrary values of the adiaba ticity parameter. The high accuracy of the formula is confirmed by comparison with the results of numerical calculations. The general case of elliptic polarization of laser radiation is also considered.
