摘要
在不同导向磁场条件下,利用电磁感应透明效应(EIT)动力学过程,在87Rb冷原子系综中进行了两正交偏振光存储和释放的实验研究。研究结果表明:随着导向磁场的增加,磁敏感自旋波对存储寿命的影响不断减小,存储寿命逐渐增大,当磁场增加到125 G时,存储寿命达到15 ms。
Abstract
Placed in different strengthes of magnetic field,the storage and release of two orthegonally polarized optical signals in 87Rb cold atoms were studied on the basis of the electromgnetically induced transparency (EIT) dynamics.It was showed that,when the Guide magnetic field increases,the magnetic sensitive spin wave on storage lifetime constantly decreases and the influence of storage lifetime increases gradually.As the magactic field rises to 12.5 G,the storage life time reaches to 1.5 ms.
