We study, in the framework of the high-frequency Floquet theory, the
one-dimensional system consisting of an electron interacting with a
symmetric two δ-functions potential in the presence of an intense
monochromatic homogeneous electric field. Most of the results concern the
attractive case. They include the dependence of
the bound states energies of the dressed potential and of some of its
resonances positions on
the electric field parameter 
(the classical free electron quiver
motion amplitude) and on the distance between the two centers and the description
of the evolution from resonances to laser induced levels via two antibound states. The repulsive case is described briefly.
