实验上对单纵模、多横模连续CO2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。

Chaos operation in a signle-longitudinal mode,multi-transverse mode CW CO2 laser caused by injected light have been studied experimentally. Tragectories in Phase-space, which of system evolving into chaos, are observed by diffential reconstructing Phase-space picture method,and some various-shape strange attractors are observed for the first time.The mechanism of laser instabilities is discussed.
