%X When laser beam is incident on an inhomogeneous isotropic plasma, the variations in density profile perpendicular to main density gradient may develop, producing a rippling of critical surface. We have discussed resonant absorption and second-harmonic generation at the rippled critical surface in the case of normal incidence. Analytic expressions for absorption and transformation coefficients are derived. It is possible to explain reasonably the deviation of linear theory from experimental results with this mechanism.
