Abstract: Excitability and relaxation oscillations are shown to appear in the vicinity of subcritical or transcritical bifurcations with a different scenario from those previously introduced in biology, chemistry and liquid-crystal physics. Experimental observation of such a scenario has been done in a laser with intracavity saturable absorber.
