Abstract / Description:We investigate harmonic generation from vacuum in the field of a superstrong standing laser wave. We show analitycally that for laser electric fields larger than Ecr = m2c3/e = 1.3 · 1016 V/cm high order harmonics of the pumping laser are generated. The harmonic spectrum shows a wide plateau followed by a cut-off at photon energies M ~ with EL the amplitude of the 6laser field. In the weak field limit EL Ecr the emission of high harmonics is very unlikely. This is now the experimentally interesting case and we show that "laser assisted" photon-photon scattering could be observed with optical lasers available today.
