Additional high-frequency components of the pulsar radiation in Crab Nebula are considered as a result of the resonance with the surface electromagnetic wave at nonlinear reflection from of the neutron star surface. This stimulated scattering consists in generation of the surface periodic relief by the incident field and diffraction of the radiation of relativistic positrons on the relief which fly from magnetosphere to the star in the accelerating electric field of the polar gap.
