Behaviour of tunnelling transition rate of argon atom exposed to strong low-frequency elliptical laser field



We considered the tunnelling ionization of an electron under the influence of a monochromatic laser beam with the elliptical polarization. Arbitrary values of ellipticity were observed. The influence of ponderomotive potential and Stark shift on the ionization rate was discussed. A brief description of the dependence of the ponderomotive potential and the Keldysh parameter on the field intensity and ellipticity is given.
