内腔He-Ne激光的磁致差拍噪声
Magnetic induced beat noise in an intracavity He-Ne laser
摘要
本文报导了内腔He-Ne激光器的一种特殊噪声,它是由空间磁场(主要是地磁)引起的。根据Zeeman激光理论和激光介质的色散特性,解释了这种噪声产生的机制和变化规律。最后给出了消除此类噪声的方法。
Abstract
This paper reports the investigation on special noise in an intracavity He-Ne laser. It is induced by a spatial magnetic field which consists mainly of earth magnet. Based on the theory of Zeeman laser and dispersion character of laser medium, the production mechanism and the regularity of magnetic induced beat noise are explained. Finally some methods for eliminating this noise are suggested.
