EFFECT OF TARGET DRESSING IN FREE-FREE TRANSITIONS IN A BICHROMATIC LASER FIELD

The influence of laser dressing of the atomic target on free-free tran sitions in a bichromatic laser field of variable relative phase is inv estigated. For simplicity, hydrogen is taken as target atom and only t he elastic, non-resonant case is considered. Exchange effects are negl ected and the scattering process is treated to the lowest-order Born a pproximation. It is found that at very small scattering angles the dre ssing effects have some influence on the phase dependence of the scatt ering cross sections in a bichromatic field.
