Paper Abstract

Theoretical consideration of the nonlinear conversion of light in photo-integrated micro- and nano-periodic susceptibility lattices which could be created in different isotropic materials is presented. The phenomena of the frequency doubling of light and the parametrical amplification of light in transformed isotropic medium are investigated according into account the realistic picture of the possible formation of the space structures of second order susceptibility with micro- and nanoperiodicities by action of the intersecting Gaussian beams of the fundamental and doubled harmonics of the mutualcoherent powerful laser radiation. The developed theory is based on a model of the formation of long-lived electrostatic field in isotropic material by means of the coherent photo-galvanic effect and gives the interesting peculiarities of processes of the frequency doubling and parametrical amplification of light which are connected with the formation of the long-lived susceptibility structures in volumetric media. In contrast to the well known nonlinear crystals, it has been demonstrated that in photo-integrated space-periodic susceptibility there is a possibility to obtain a new regime of twobeam frequency conversion of light. Fundamental properties of the phenomena have been studied and the possible mechanisms of processes are discussed.
