摘要

It follows from above consideration that the circular and elliptical laser polarizations are more preferable for the experimental investigation of the relativistic effects in the energy and angular spectra of ejected electrons at He tunneling ionization than the linear laser polarization. However, in the case of the linearly polarized field the relativistic effects begin to be important at the relatively small kinetic energies of the ejected electron compared to its rest energy. All obtained results are valid both for tunne ing ionization and for barrier-suppression ionization by super-intense laser field,but in the latter case exponents should be substituted everywhere by the Airy functions assording to the simple rule (see Ref.[5]for details) exp(-x)→Ai(3x/2)~(2/3)]. The main qualitative relativistioc effects for circular and elliptical polarization are: 1) The relativistic increasing of the peak in the energy spectrum of ejected electrons; 2) The preferential ejection of electrons out of the polarization plane of laser radiation. Our discussion restricts only by the case of direct ionization of relativistic electrons. This is the relatively low-energy part of the electron energy spectrum.We did not consider the rescattering processes which produce plateau of hot electrons. This problem is unsolved up to now for relativistic electrons. This work was supported by the research grant N 99-02-17810 of the Russian Foundation for Fundamental Research.
