Quantum Beat Spectroscopy using Tunable Pulsed Dye Lasers
The recently developed broadly tunable N2 — laser pumped pulsed dye lasers are an ideal source of light excitation for Quantum Beat experiments. Using one of these lasers, we have observed optically induced hyperfine Quantum Beats in the 72P3/2 state of Cs . This experiment shows that the detection of dye laser induced Quantum Beats may be developed as a practical tool in high resolution spectroscopy without Doppler effect. Some speculations regarding future applications of the technique are considered.

- 11.In order to get accurate values of the hyperfine splittings, one would also have to cancel the earth magnetic field which was applied to the atoms at the time the spectra of Fig. 6 were recorded. This field splits the hyperfine levels in several components and thus broadens the peaks in the Fourier spectra. This effect was overlooked in this experiment because its resolution was in any case limited by the existence of a large interval between points in the spectra. In the study of the high lying Cs p states described below, the magnetic field perturbation will become much more important, due to the smaller value of the hyperfine coupling in these states. Consequently, the earth field will be carefully cancelled out in these experiments.Google Scholar
