摘要
设计并实现了频差为9.2GHz的两束光在三镜环形腔内的双共振频率锁定及输出两束光的空间分离。当腔长精确控制为391.3mm时,频差9.2GHz的两束光在三镜环形腔内达到双共振。与此同时,利用不等臂马赫-曾德尔(M-Z)干涉仪,在两臂光程差为81.5mm且相位差为π/2时,实现了对两束光的空间分离。该装置为实现腔内原子相干效应介质中的光量子态交换奠定了实验基础。
The lock of double resonance frequency and spatial separation of two lights with frequency difference of 9.2 GHz in a three-mirror ring cavity and Mach-Zehnder （M-Z） interferometer are designed and confirmed. The double resonance for the two lights is accomplished when cavity length is 391. 3 ram, and frequency difference is 9.2 GHz. And then, the two beams are spatial separated with unbalanced M-Z interferometer whose two arms optical path difference is 81.5 mm and phase difference is n/2. The device lays an experimental foundation for the realization of the optical quantum exchange with a coherent atomic medium in an optical cavity.
