横向磁场导致CO_2激光器混沌运转及其奇异吸引子的观测

CHAOS AND OBSERVATION OF STRANGE ATTRACTOR IN CO_2 LASER WITH TRANSVERSE MAGNETIC FIELD

在外加磁场的情况下,对单模均匀展宽CO_2激光器进行了实验研究。改变磁场的大小,观察到了自脉动和混沌现象,同时还获得了该系统的奇异吸引子,并对其物理机制进行了探讨。

We have experimentally studied the instabilities of a homogeneously broadened single-longitudinal mode CO2 laser with transverse magnetic field. Self-pulsing and chaos have been observed by varying the magnetic field. The strange attractor of the laser system has also been obtained. A discussion is made on the mechanism of the phenomena observed.
