Paper Abstract

Self-pulsating, irregular fluctuations and deterministic chaos in the output intensity produced by a BaTiO3 self-pumped phase conjugate mirror has been observed. The behaviour is seen to vary with the incident laser intensity and especially with the specific region of interaction within the probe, which can be influenced by the orientation of the crystal with respect to the input beam. Q uaiitative examinations of the nature of these fluctuations - like the Fourier transform and the autocorrelation function - show signs for deterministic chaotic behaviour. As a qualitative analysis method of nonlinear dynamics, the Grassberger-Procaccia analysis is carried out to compute a lower bound of the Hausdorff dimension of the temporal field. That dimension varies with the critical input parameter, the region of interaction, between 2.25 and 8.5 and allow thus conclusions on the theoretical model needed to describe the system.
