Abstract An {ital analytical} solution is found for the lowest Floquet state in a single quantum well which is strongly driven by an external laser field of form {ital eFz}cos{omega}{ital t}. The spectral weights of the photon sidebands vary in a highly nonlinear fashion with {ital F}, exhibiting strong quenchings close to roots of the Bessel functions {ital J}{sub {ital n}}({ital k}{sub 0}{ital eF}/{ital m}{omega}{sup 2}), where {ital n} is the sideband index and {ital k}{sub 0} is the wave vector of the centerband resonance. The {omega}{sup {minus}2} scaling behavior of the roots is qualitatively different from the {omega}{sup {minus}1} dependence found in the coherent miniband transport in superlattices. {copyright} {ital 1996 The American Physical Society.}
