Ellipticity-dependent ionization yield for noble atoms Project supported by the Science Foundation from the Serbian Ministry of Education, Science and Technological Development (Grant No. 171020)

The photoionization in the frame of the Ammosov-Delone-Krainov theory has been theoretically examined for noble gases, argon, krypton, and xenon, in an elliptically polarized laser field. We consider the intermediate range of the Keldysh parameter, γ ∼ 1 , and analyze the influence of shifted ioniza...

Summary:The photoionization in the frame of the Ammosov-Delone-Krainov theory has been theoretically examined for noble gases, argon, krypton, and xenon, in an elliptically polarized laser field. We consider the intermediate range of the Keldysh parameter, γ ∼ 1 , and analyze the influence of shifted ionization potential and temporal profile to eliminate disagreement between theoretical and experimental findings. By including these effects in the ionization rates, we solve rate equations in order to determine an expression for the ionization yield. The use of modified ionization potential shows that the ionization yields will actually decrease below the values predicted by original (uncorrected) formulas. This paper will discuss the causes of this discrepancy.
