摘要
光学泵浦单模环形铵分子激光器能显示包括信周期分岔混沌 ,间歇性混沌以及类洛仑兹螺旋形混沌等各种混沌动力学特性 ,基于该激光器的混沌特性 ,作者设计了不同的实验研究耦合混沌系统间的相互作用 ,文中报道了研究结果 ,展示了以下方面的实验证据 :单向耦合混沌系统间的频率锁定及广义混沌同步双向耦合混沌激光模间的反位相频率锁定 ,反位相混沌同步以及完全严格混沌同步。通过分析所观察到的不同混沌同步形式 ,得出耦合混沌系统间同步的物理起源仍然是系统间的位相相互作用 。
The optically pumped NH 3 single mode ring laser can exhibit various types of chaotic dynanics.These include the period-doubling chaos,intermittency and the Lorenz-like spiral chaos.Based on the chaotic dynamics of the laser the author has designed experiments to study the interaction between coupled chaotic systems.In this paper he reports on results of his investigations.He demonstrates experimental evidence of frequency entrainment and generalized synchronization of chaos between unidirectionally coupled chaotic laser,and the antiphase frequency entrainment,antiphase chaotic synchronization and perfect chaotic synchronization between mutually coupled chaotic laser modes.Analyzing properties of the various forms of chaotic synchronization observed he speculates that the physical origin of sychronization between coupled chaotic systems is the phase interaction between the coupled chaotic evolutions.In particular,the different forms of chaotic synchronization observed are results of different stages of chaotic phase locking.
