Abstract
Tm:YAlO₃ lasers suffer from self-pulsing. A four-level rate equation analysis suggested that the self-pulsing could be due to excited-state absorption. We report a measurement of the cross section for this absorption and show that it is too small to be the sole cause of the self-pulsing. We propose nonlinear dynamical chaos as an alternative explanation and present a chaos analysis of the output of a cw-pumped Tm:YAlO₃ laser, including experimental evidence of chaos.
