Calculation of the binding energy of an off-center donor hydrogenic impurity in a cylindrical quantum wire, in the simultaneous presence of an intense high frequency laser field and a static magnetic field, is reported. Different geometries concerning the size of quantum wire, the donor impurity position, as well as the polarization direction of the applied laser field with respect to the quantum structure, were considered. We found that in the strong confinement regime the presence of the linearly polarized laser radiation resolves partially the degeneracy of donor states corresponding to symmetrical position of the impurity.
