Description

Electron-positron pair production in a strong laser field enhanced by an assisted high frequency weak field is investigated by solving the quantum Vlasov equation. The average and residual pair number densities are obtained for sinusoid electric field and it is found that the high frequency assisted weak field will enhance pair production significantly. There exists an optimal frequency of assisted field that makes the pair production number density get a maximum one, which is a few orders of higher than that without assisted field. We also discuss the other possible assisted fields. (physics of elementary particles and fields)
