Single-mode and multimode self-pulsing instability leading to chaos is reported in the 12.8-..mu..m emission from a homogeneously broadened NH/sub 3/ laser, near resonantly pumped by CO/sub 2/ laser radiation. Occurrence of instabilities on two independent emitting transitions over a wide range of operating conditions, including those for optimum lasing, indicate that this behavior is general for near resonantly enhanced two-photon Raman systems of this type.
