Two coupled complex Ginzburg-Landau equations are derived to described multimode operations of a ring unidirectional laser with a saturable absorber near the lasing threshold. We show that unlike a laser without absorber this laser can exhibit in low-intensity domain the Benjamin-Feir instability which is known to lead to very complicated behaviors including chaotic ones.
