POTENTIAL SCATTERING OF ELECTRONS IN A BICHROMATIC LASER FIELD OF FREQUENCIES-OMEGA AND FREQUENCIES-2-OMEGA OR FREQUENCIES-OMEGA AND FREQUENCIES-3-OMEGA

Potential scattering of electrons in a bichromatic laser field is cons idered. The field will either have frequencies omega and 2omega or fre quencies omega and 3omega. In both cases the two components will be ou t of phase by an angle f. As a function of f the electron scattering s pectra will be very different for the two cases. If we have omega and 2omega, the electron spectra may show pronounced asymmetries for parti cular values of f whereas for omega and 3omega, the spectra will be sy mmetric, but, for a particular f the central peak of the electron spec trum may be strongly suppressed. For presently available experimental facilities such effects should become observable.
