摘要

We have observed the conversion of CW laser Ar-ion beam power into pulsating multichannel outputs: optical, electric and piezoelectric with simultaneous dynamic pattern formation. Frequencies of multi-channel pulsations have characteristic sigmoidal dependence (with threshold) on laser intensity. We have also demonstrated the possibility of synchronization of two optical pulsators, through regulated optical coupling in a photorefractive LiNbO_3 crystal. Spatial distribution of scattered light is selforganized in different patterns (hexagonal and cross-type).
