Abstract

The effect of the relative phase between the components of a bichromatic field of frequencies $\omega$ and $3\omega $ is discussed in the case of free-free transitions in laser-assisted electron-hydrogen scattering. For fast projectile and low field intensities, the role of target dressing is pointed out.
