Dynamical Instabilities, Chaos And Spatial Complexity In Fundamental Nonlinear Optical Interactions.
Abstract
Experimental and theoretical investigations address nonlinear dynamics and complexity in basic nonlinear optical interactions. Notably contributions include (a) first demonstration of chaotic dynamics of stimulated Brillouin scattering (SBS) confirmed through the latest dynamical measurement tools (b) stochastic effects shown to dominate dynamics for cavityless operation but to be suppressed for SBS with feedback (c) first generalised treatment of stimulated scattering in which deterministic dynamics and chaos are shown to be inherent features of behaviour consistent with experimental findings (d) first evidence of patterns, singularities and turbularie in SBS through multi transverse mode interactions (e) generalised analysis of transverse patterns and instabilities of diffraction-diffusion type systems in nonlinear optics - ongoing (f) low frequency (MHz) dynamics and chaos in diode lasers with feedback and in NdYAG modulated lasers - ongoing (g) control of chaos in diode lasers and development of new all optical control algorithms - ongoing (h) lasing without inversion in V systems and (i) new approach to the theory of radiation matter interactions for arbitrary field strength.
