Chaotic Phenomena in a Two-Photon Laser with Injected Signal

The instability and the chaotic phenomena in a two-photon laser with injected signal are discussed for the homogeneously broadened single mode ring cavity. The structure of the system's attractors is considered by using the Lyapunov exponents and the Lyapunov dimension. The strange attractors of chaos and superchaos are found. The strange attractor displaying superchaos is not observed in one-photon laser with injected signal.
