Paper Abstract

The nondegenerate three-wave process of second harmonic generation under exact phase matching and of different amplitudes and polarizations of interacting waves is considered experimentally in KTiOPO4 crystal. The central part of the weaker pulses of fundamental frequency and of the second harmonic oscillates periodically both in spatial and temporal domain. The complete transformation to the second harmonic and back, accompanied by (pi) -changing of the phase of carrier frequency, at every cycle is observed. Clear beam canalling is observed too.
