Chaotic Attractor in Dynamics of Thermal Lens Pattern

Abstract

Thermal lens oscillations have been studied and characterized by periodicity, quasiperiodicity, period doubling, frequency locking and chaos, with control parameters of temperature, laser power and geometry. An embedded chaotic attractor theory has been developed using fluid dynamics and nonlinear dynamics. The paper reports preliminary characterization of the experimental chaotic attractor and main features of the theoretical model.
