亚稳跃迁强激发下单离子的量子相干性

Quantum Coherence in a Single Ion due to strong Excitation of a metastable Transition

J. von Zanthier, C. Skornia, G. S. Agarwal, H. Walther

摘要:

我们考虑泵浦-探测光谱的一个高度亚稳态(探测)的时钟跃迁,这是通过使用量子跳跃技术监测的单个离子。对于弱时钟激光,我们得到了著名的Autler-Townes分裂。对于更强的功率的时钟激光器,我们证明了过渡到一个新的制度。这两个政权的区别是过渡的两个复杂的本征值,以纯粹的虚数,可以是非常不同的幅度。跃迁由时钟激光器的功率控制。对于泵浦共振,我们提出了简单的解析表达式为各种线宽和线的位置。

英文摘要:

We consider pump-probe spectroscopy of a single ion with a highly metastable (probe) clock transition which is monitored by using the quantum jump technique. For a weak clock laser we obtain the well known Autler-Townes splitting. For stronger powers of the clock laser we demonstrate the transition to a new regime. The two regimes are distinguished by the transition of two complex eigenvalues to purely imaginary ones which can be very different in magnitude. The transition is controlled by the power of the clock laser. For pump on resonance we present simple analytical expressions for various linewidths and line positions.
