弱磁场下法拉第效应的实验研究及可能应用讨论
Experimental research of Faraday effect in a weak magnetic field and its possible applications
摘要
利用了四频环形激光对磁场的高度敏感性测量了Tb玻璃(磁场范围0.8×10~(-5)T(Tesla)～10~(-9)T,ZF_2玻璃(0.21×10~(-4)T～1.89×10~(-4)T的费尔德常数(Verdet constant).在本实验精度范围内,得到了该常数大小和强磁场下的值一致.以此实验结果为基础,简要地讨论了用置于环形激光中的法拉第磁光材料感测地磁场的构思和发展前景.
Abstract
The high sensitivity of a ring laser is used for measuring Verdet constants V of Tb glass and ZF2 glass in a weak field. The measurement results show that the value of V in a weak field coincides with that in a strong field. Based on the results, possible applications in sensing the earth magnetic field by placing Faraday magneto-optics glass in a ring laser are discussed.
