摘要：
We show that for potential scattering of electrons in a bichromatic laser field a Kroll-Watson type of theorem can be derived in which the scattering T-matrix element is composed of a renormalized on-shell matrix element for scattering without a field times a generalized Bessel function factor. The radiation field has two components of frequency omega1 and somega1 (s = 2, 3, ...) and both components are out of phase by an angle phi. Our paper is a generalization of earlier investigations which were performed in the first-order Born approximation.
