We consider laser-stimulated resonance scattering of electrons in a bi
chromatic laser field in the framework of a one-dimensional potential
model. The two fields have the frequencies omega and 2 omega and are o
ut of phase by phi. Changing phi permits us to coherently control the
shape and height of the resonance peaks: in particular, a pure Breit-W
igner distribution can be obtained.
