Features of the energy spectra of photoelectrons at the atomic ionization in a twocolor laser field of first and third harmonics
Abstract
Classical analysis and quantummechanical studies of the energy spectra of photoelectrons have been carried out for abovethreshold ionization of atoms in a twocolor laser field of the first and third (n = 3) harmonics. Numerical computations show that the boundary of direct ionization plateau corresponds to the electron energy E {approx} 3.56 U{sub p{sub 1}}, while the boundary of rescattering plateau corresponds to the electron energy E {approx} 16.62 U{sub p{sub 1}} for the twocolor field of fundamental frequency and its third harmonic with equal intensities, which is in accordance with the results of classical analysis. The results of classical analysis of the ionization processes in the field of first and nth harmonics of equal intensities show that the length of the direct ionization plateau and the length of the highenergy rescattering plateau decrease with increasing n. The results of numerical analysis of the ionization processes in the field of first and third (n = 3) harmonics correspond to the results of classical analysis carried out by the authors.

Efficient highorder harmonic generation was obtained in helium below 10 nm using a linearly polarized twocolor field consisting of a Ti:sapphire laser pulse ({omega}) with a 40fs duration and its second harmonic (2{omega}) with a 24fs duration. The intensity of the twocolor harmonics was enhanced more than that of the {omega} or 2{omega} field alone by more than one order of magnitude along with the extension of the cutoff order and the generation of efficient evenorder harmonics. This observation was explained by the contribution of the lower branch rather than the upper branch of the cutoff energy, which are splitmore »

Generation of submicrojoule high harmonics using a long gas jet in a twocolor laser field
We have achieved very efficient highharmonic generation in a twocolor laser field using a long gas jet of He. With the optimization of laser parameters and target conditions, strong harmonics were produced at 2(2n+1)th orders in an orthogonally polarized twocolor field. The strongest harmonic at the 38th order (21.6 nm) reached an energy of 0.6 {mu}J with a 6 mm gas jet, giving a conversion efficiency as high as 2x10{sup 4}. 
Energydependent photoelectron angular distributions of twocolor twophoton above threshold ionization of atomic helium
Energydependent photoelectron angular distributions from twocolor twophoton above threshold ionizations are investigated to determine the partialwave characteristics of freefree electronic transitions in helium. Sideband photoelectron energies ranging from 0.18 to 13.0 eV are measured with different wavelengths of the perturbative infrared dressing field as well as different individually selected highorder harmonics. Using the experimentally measured crosssection ratios and anisotropy parameters together with analytical expressions derived from secondorder perturbation theory, the partialwave branching fractions going to the S and D waves in the positive and negative sidebands are determined as a function of photoelectron kinetic energy. The results provide a sensitivemore » 
Multiphoton processes in an intense laser field. VI. Twocolor ionization with incommensurable frequencies
We present results of Floquet calculations of rates and yields for ionization of atomic hydrogen, in its ground state, in the presence of a relatively weak highfrequency field and a relatively strong lowfrequency (1064nm) field. We assume that the two frequencies are incommensurable, or, if they are not, we average over the relative phase. We explore three processes: (i) Resonanceenhanced ionization, via levels that are acStark mixed or/and very strongly shifted, (ii) laserinduced continuum structure, and (iii) nonresonant ionization in a regime where, despite the fact that the infrared field significantly shifts the ground state relative to the continuum, itmore »
