Abstract
A cw C laser with a predominantly homogeneously broadened lasing transition is shown to lose its stability under certain values of cavity detuning when more than two transverse modes are excited. The instability dynamics is found to be strongly dependent on the excited modes. In particular, we have observed period-doubling bifurcations, followed by periodic windows, and a frequency locking of two fundamentals at some rational ratio.
