实验上对单纵模、多横模连续ＣＯ_２激光器由注入光引起的混饨运转进行了研究。利用微分重构相空间法对系统在演化成混饨态时的相空间轨道进行了观测，并首次观察到在注入光条件下不同横模结构所对应的形状各异的奇怪吸引子，通过分析它们的结构对由光注入引起非稳性的物理机制进行了讨论。 Experiments on the single longitudinal mode, multi-transverse mode continuous CO_2 laser by the injection of light caused the chaff operation. The differential space reconstructed phase space method was used to observe the phase space orbit when the system evolved into a mixed state. The strange attractor with different shapes corresponding to different transverse mode structures was observed for the first time. Their structure discusses the physical mechanism of instability caused by light injection.
