These structures are associated to saddle-node bifurcations. We found that these phenomena can be properly explained in the framework of saddle-node bifurcation cascade. Apparently not connected phenomena in these lasers are shown to be related within this framework.One TeX file and 3 EPS figuresChaotic Dynamicstext
