Abstract Title: Two-laser Spectroscopy in Atomic Cesium
Abstract: Inexpensive, narrowly tuned diode lasers have been often used to introduce students to modern spectroscopy, with saturation spectroscopy of alkali D lines becoming a standard undergrad research project. For labs which could afford more than one such diode laser, we propose a two-quantum two-color spectroscopy experiment in which relative strengths of atomic transitions can be determined. The relevant ratios of transition probabilities can be also modeled using simple quantum mechanics, so the theoretical and experimental results can be compared and discussed. Using the same set-up, a step-wise excitation with narrow-line lasers can be conducted, and provide clear evidence for velocity-selective atomic excitation and Doppler shift proportionality to the atomic transition frequency.
