THE TRANSVERSE PATTERN OF LASER OSCILLATION OUTPUT IN A RING CAVITY AND THE TRANSITION TO OPTICAL TURBULENCE
环形腔中激光振荡输出的横向斑图及向光学湍流的转变

Based on the earlier theoretical work on the bifurcation and chaos of laser oscillation output in a ring cavity, we present in this paper a study of transverse effects in the spatially extended system. Numerical simulations show that the spatially extended system has the homogeneous stationary states, the traveling wave solutions and the spatiotemporal chaos states with the change of its parameters. We also find a transition to turbulence via symmetry breaking at the definite system parameters when considering incident light as plane wave (homogeneous distribution).
