SIMULTANEOUS MEASUREMENT OF ABSORPTION-LINES FOR RIGHT AND LEFT CIRCULARLY POLARIZED FIELDS USING SATURATION SPECTROSCOPY

Abstract

By employing a Doppler-free saturation spectroscopic method, absorption lines for the left and the right circular polarizations have been measured simultaneously at the sodium D1 line that was pumped by a circularly polarized beam. These experimental results are compared with theoretical results obtained with the velocity-selective optical pumping effect in a four-level atomic system. The effects of the pump-beam intensity on the signal spectra are also investigated.
