Abstract
A new spectral method for surface investigation based on optical-phase conjugation in an unexcited transparent medium is theoretically developed and experimentally verified. On YAlO3:Nd (1 at %) single crystals at room temperature, the phase conjugation of light is revealed for a photon energy equal to half the energy of resonant local oscillations of electrons of impurity centers. The dependences of the intensity of the phase-conjugation signal of light on its spectral structure are investigated. An explanation of the effect of the Raman scattering of light electromagnetic waves by neodymium ions is offered.
