Instability of He-Ne Laser With External Optical Feedback
摘要
报道了平面镜和自泵浦相位共轭镜反馈He-Ne激光器的非稳特性,观测了反馈镜位置对激光光强起伏及波动频率的影响,即在半腔长的整数倍附近,激光光强具有较大的起伏和秒量级的准周期振荡,并对其产生机理进行了分析。
Abstract
The instability characteristics of a He-Ne laser with plane mirror and self-pump phase conjugation feedback are studied. The effects of distance between the feedback mirrors (plane mirror or phase conjugate mirror) and laser on the laser intensity fluctuation and fluctuation frequency are abserved. We find that laser intensity has large fluctuation and quasi-periodic oscillation of seconds order when the feedback mirror is at integer multiple of half cavity length. Its mechanism is analyzed.
