The Contribution of the Atomic Excitation and Recollision Effect during Tunneling Ionization on the Transition Rate

摘要: We used the Dykhne formalism to develop an analytical model for correlated simultaneous ionization excitation process of two-electron helium-like atoms in a strong laser field, and then analyzed contribution recollision effect on transition rate linearly polarized field. Also, we briefly discussed circularly were interested examine how atomic affect because observations indicated significance both processes tunneling radiation. showed that, under conditions considered here, aforementioned effects play important role and, therefore, must be taken into account case linear polarization, while do not circular polarization.
