Abstract

We have observed the nonlinear magneto-optic effect(NMOE) based on atomic coherence in $^{87}$ Rb D$_1$-line using the Rb vapor cell containing 50 Torr of Ne. The width of the NMOE signal was measured to be 2$\pi$${\times}$464 Hz, when the peak-to-peak B-field variation was 1 mGauss. The result of this work may be applied to a high-sensitivity magnetometer.

우리는 버퍼 가스가 포함된 Rb 원자 증기셀을 이용하여 $^{87}$ Rb원자 D$_1$전이선에서 원자결맞음에 의한 비선형 광자기 신호를 관측했다. 측정된 가장 좁은 비선형 광자기 신호의 선폭은 2$\pi$${\times}$464 Hz이고, 이 때 비선형 광자기 효과에 의한 미분형 신호의 peak-to-peak 변화에 해당하는 자기장의 변화는 약 1 mGauss로 측정되었다. 이러한 결과는 고감도 자기장 측정을 위한 광자계 연구에 응용될 수 있다.
