使亚稳态氙的光学产生最大化
Maximizing optical production of metastable xenon
摘要:
使用亚稳态惰性气体原子的广泛应用导致了许多不同的方法来产生大的亚稳态密度。在这里,我们研究了最近提出的混合方法,结合射频放电技术与光泵浦从辅助状态氙。我们研究了氙气压对射频放电建立辅助态和亚稳态初始布居的影响,以及光泵浦功率对两态间布居转移的作用。我们发现实验条件,最大限度地提高效果,并提供了一个强大的平台,产生相对较大的长期亚稳态密度。
英文摘要:
The wide range of applications using metastable noble gas atoms has led to a number of different approaches for producing large metastable state densities. Here we investigate a recently proposed hybrid approach that combines RF discharge techniques with optical pumping from an auxiliary state in xenon. We study the effect of xenon pressure on establishing initial population in both the auxiliary state and metastable state via the RF discharge, and the role of the optical pumping beam power in transferring population between the states. We find experimental conditions that maximize the effects, and provide a robust platform for producing relatively large long-term metastable state densities.
