Ionization of hydrogen atom in the field of high-intense ultra-short femto-second laser pulse recently became the subject of comprehensive theoretical approaches. On the other hand, there exists experimental evidence that short electric pulses can effectively stimulate electron-proton (as well as antiproton-positron) recombination to high-level (Rydberg) state. In this paper we present the results of the theoretical estimations of antiproton-positron recombination cross-section in cold mixed plasmas in traps in the conditions of ATHENA/ATRAP experiments in CERN under the action of sub-fs laser pulse with TW intensity.
