Abstract

A system is designed to observe the phenomena of electromagnetically induced transparency and optical pumping in cesium D1 and D 2 lines at room temperature. When a pump laser is frequency-locked on the top of a hyperfine transition and the frequency of the probe laser scans over another hyperfine transition, a spectrum of V-type electromagnetically induced transparency or an optical pumping can be observed depending on whether the two lasers share a common ground state. Therefore, these results can be used to identify the unknown hyperfine transitions of the D1 line transitions. For educational purposes, this system is helpful for understanding the electromagnetically induced transparency and the optical pumping.
