New Aspects of Instabilities and Chaos in Laser Systems
The phenomena to be described occur in nearly all types of laser systems, though with large differences in pump intensity: in single mode and multi-mode lasers, in lasers with homogeneously or inhomogeneously broadened lines, in lasers with or without external drive or feedback, in lasers with and without saturable absorbers. As. in all other dynamic systems with similar instability behaviour, the observed effects are results of internal selforganization, possibly by interplay with an external triggering. They appear above a second threshold, the first one being the threshold between incoherent emission and stable laser activity. The main characteristics are gradually enhanced: selfpulsing of the laser output under constant laser conditions, regular at first, then irregular and chaotic with growing intensity, or bistability going to multistability, hysteresis included, frequency pulling and locking, phase locking also.
