本文研究了环形腔激光系统的反馈延迟对该系统的不稳定输出阈值,时间波形,功率谱及向混沌过渡道路的重要影响.着重分析了短延迟情况下输出场向混沌态的过渡,讨论了此情况下不出现高阶分岔的原因,并通过详细的数值计算把短延迟与无限大延迟两种情况联系起来.

This paper studies the important effect of feedback delay on the unstable output of ring cavity laser system, especially the route to chaos in small delay time. The reason for higher bifurcations having not been found in small delay time is analyaised, and the routes to chaos in both small and large delay time are connected by numerical calculation.
