ABSTRACT

Nonlinear selective reflection of obliquely incident laser beam (inclined geometry) has been investigated. The new structures were detected on the tops of strong reflection resonances under conditions of optical saturation of the D2-lines in the natural mixture of rubidium isotopes. The detected nonlinear structures have not saturation properties in usual sense and exist only in the close area of saturating power density values. This phenomenon can be useful for the amplification the nonlinear characteristics of the optical interface in order to reduce the fluctuations of selective reflected light.
