RADIATIVE RECOMBINATION IN THE PRESENCE OF A FEW CYCLE LASER PULSE

Abstract

We have investigated the laser-assisted radiative recombination in the presence of a few-cycle pulse with the aim of demonstrating means of controlling such process. Within the Coulomb-Volkov approach already employed to describe the radiative recombination assisted by a monochromatic laser field, we have found that the emitted photon spectrum is affected by both the cycle number n(c) and the carrier-envelope relative phase.. In particular, it has been shown that the minimum and the maximum values of the emitted photon energy may be controlled by varying nc and.. Finally, it has been found that the enhancement of radiative recombination occurring in the presence of a monochromatic field, takes place also by using a few-cycle laser pulse.
