Title: “Nonlinear dynamics of experimental laser systems including complexity analysis”	
Abstract
It is an exciting time in the field of analysing output power time series from nonlinear laser systems. Advances in real time oscilloscopes mean that the time resolution of the output power is sufficient to study all but the fastest semiconductor lasers. Advances in computer control of experimental laser systems mean that high density data sets, to support the generation of high resolution maps of the dynamics, are increasingly available. Advances in applying complexity analysis tools to experimental output power time series are starting to generate almost complete dynamic maps for systems based on correlation dimension and/or permutation energy. Additionally, analysing other experimental observables such as the peak to peak amplitude, average period/frequency for pseudo-pulsed data, fluctuations in the “period”, and searching for regions where the dynamics show transients, all add to a more complete evaluation of an experimental system, and support robust comparison with theoretical models for the systems. An overview of these recent advances applied to several different laser
systems will be given.
