Abstract :
The coherence times and critical feedback rates are calculated for a coherence collapsed single-mode semiconductor laser with external optical feedback. It is shown that, in contrast to what is suggested by certain numerical simulations, coherence collapse need not disappear when the linewidth enhancement parameter vanishes
