INFLUENCE OF NOISE ON CHAOTIC LASER DYNAMICS

The Nd:YAG laser with an intracavity second harmonic generating crysta l is a versatile test bed for concepts of nonlinear time series analys is as well as for techniques that have been developed for control of c haotic systems. Quantitative comparisons of experimentally measured ti me series of the infrared light intensity are made with numerically co mputed time series from a model derived here from basic principles. Th ese comparisons utilize measures that help to distinguish between low and high dimensional dynamics and thus enhance our understanding of th e influence of noise sources on the emitted laser light.
