Abstract
Calculation of the binding energy of an axial donor hydrogenic impurit y in an ideal, infinite, cylindrical quantum wire placed in an intense , high-frequency laser field is reported. By making use of a nonpertur bative theory that ''dresses'' both the potential of the impurity and the confinement potential in the quantum wire, and the variational app roach a rapid decrease of the binding energy for different values of t he wire radius with increasing field intensity is predicted.
