Experimental evidence of three-mode quasiperiodicity and chaos in a single longitudinal, multi-transverse-mode cwCO2laser

Abstract
We report observation of oscillatory instabilities leading to chaos in a single longitudinal but multi-transverse-mode cw CO2 laser. Particularly interesting is the observation of stable oscillation involving three transverse modes en route to chaos. Furthermore, these results are obtained under predominantly homogeneously broadened lasing transition.
