Clark Vandam, Aaron Hankin, A. Sieradzan, M. D. Havey

摘要:

我们目前的结果多光路量子干涉项目适合于先进的本科实验室。这些实验结合了一组概念丰富的原子物理学实验,这些实验可以在本科物理或工程专业的技术水平上经济地开发。在实验中,二极管激光驱动的双量子,双色激发的铯原子的蒸气室进行了研究和个别的超精细成分的相对强度的$6s^{2}S_{1/2} \rightarrow 7s^{2}S_{1/2}$过渡确定。两个量子激发速率的光谱变化的测量和分析清楚地表明,由于在整个过渡振幅的干扰振幅的强烈变化。像这里报道的这样的项目允许对实验和理论物理学感兴趣的本科生组成的小团队来构建仪器,进行复杂的实验,并对结果进行逼真的建模。

英文摘要:

We present results on a multiple-optical-path quantum interference project suitable for the advanced undergraduate laboratory. The experiments combine a conceptually rich set of atomic physics experiments which may be economically developed at a technical level accessible to undergraduate physics or engineering majors. In the experiments, diode-laser driven two-quantum, two-color excitation of cesium atoms in a vapor cell is investigated and relative strengths of the individual hyperfine components in the $6s^{2}S_{1/2} \rightarrow 7s^{2}S_{1/2}$ transition are determined. Measurement and analysis of the spectral variation of the two quantum excitation rate clearly shows strong variations due to interfering amplitudes in the overall transition amplitude. Projects such as the one reported here allow small teams of undergraduate students with combined interests in experimental and theoretical physics to construct instrumentation, perform sophisticated experiments, and do realistic modelling of the results.
