Doppler-free laser spectroscopic techniques with optical pumping in D_1 lines of alkali atoms

Shigeru Nakayama

A theoretical analysis of the D1 lines of alklai atoms in Doppler-free polarization spectroscopy, velocity-selective optical-pumping (VSOP) spectroscopy, and saturation spectroscopy is presented that uses the approximation of a single cycle of optical pumping in a four-level system. The similarities and differences among these three kinds of spectroscopy are made clear, and the magnitude and the sign of the resonances in each spectroscopic technique are calculated. The four-level system is as important as a three-level approximation, which has already been described in many papers. We deal with linear and circular optical anisotropies induced in polarization, VSOP, and saturation spectroscopy.

Theoretical Analysis of Rb and Cs D2 Lines in Doppler-Free Spectroscopic Techniques with Optical Pumping

Shigeru Nakayama

The relative intensities of the Doppler-free signals of the 85Rb and Cs D2 lines in saturation spectroscopy, velocity-selective optical pumping (VSOP) spectroscopy, and polarization spectroscopy were calculated theoretically, taking into accont the optical pumping process in the Zeeman sublevels and arbitrary polarization combinations for pump and probe beams. Both circular and linear optical anisotropy induced by the pump beam were considered in the theoretical calculation. The magnitude and sign of the Doppler-free resonances in each spectroscopic method were quite different owing to the polarizations of the pump and probe beams. The theoretical results obtained from a single-cycle optical pumping in a four-level approximation were in good agreement with recent experimental reports.
