Abstract :
The three-wave conversions ( such as the nonlinear generation of light pulses of second harmonic frequency and parametric amplification of light signals), photo-induced in all-optically polled glasses materials, have been investigated. Theoretical considerations of the investigated phenomena show the interesting peculiarities of the process of three-wave conversions in photo-integrated volumetric micro-structures of nonlinear polarizability with the existence of a regime of synchronous two-beam transformations of light pulses. During the experimental investigation of the phenomena in the bulk oxide glasses the complicated kinetics of the formation of second-order polarizability gratings has been detected. Some properties of the phenomena have been studied and the possible mechanisms of the dynamics of processes are discussed.
