摘要

碱金属原子的磁诱导（MI）跃迁之所以引起人们的兴趣，是因为它们的强度可以在很宽的磁场范围（200-4000 G）内超过 "常规 "原子跃迁的强度。这项工作的目标是利用调谐到 MI 转变的探针辐射，首次在强磁场中形成并研究电磁诱导透明（EIT）共振，而这种共振在零磁场中是禁止的。利用两束窄带线性偏振 cw 二极管激光器，在强横向磁场（高达 1000 G）中的 Cs 原子 D2 线的Λ型系统上形成了 EIT 共振。共振是在原子蒸气柱厚度为 850 nm 的 Cs 原子蒸气纳米电池中形成的。

Electromagnetically induced transparency with magnetically induced ΔF=0,mF=0→mF=0 probe transition

Interest in magnetically induced (MI) transitions of alkali metal atoms is caused by the fact that their intensities can exceed the intensities of ‘regular’ atomic transitions in a wide magnetic field range (200–4000 G). The goal of this work was to form and study, for the first time, electromagnetically induced transparency (EIT) resonance in a strong magnetic field using probe radiation tuned to MI transition, which is forbidden in zero magnetic fields. Two narrow-band linearly polarized cw diode lasers were used to form EIT resonance on a Λ-type system of a Cs atomic D2 line in a strong transverse magnetic field (up to 1000 G). The resonance was formed in a Cs atomic vapor nanocell with an atomic vapor column thickness of 850 nm.
