摘　　要：本文首次在实验上对单纵模、多横模连续CO_2激光器由注入信号所引起的非稳性进行了研究。观察到了系统输出的频率漂移和混沌运转等现象,利用微分重建相空间图方法观察到了在光注入的条件下混沌态所对应的奇怪吸引子,并对由注入光引起的非稳性的物理机制进行了讨论。Instabilities in a signle-longitudinal mode, multi-transverse rnode CW CO_2laser caused by injected light have been studied experimentally for the firsttime. The phenomena of pulsing frequency shift and chaos are observed experi-mentally, strange attractor is observed by diffential reconstructing phase-spacepicture method. The mechanism of laser instabilities is discussed.
