Observation of Light-Induced Drift Effect of Rubidium by Using Two Diode Lasers for Pumping and Re-Pumping

Abstract

The light-induced drift (LID) of rubidium was demonstrated by using two diode lasers for the pumping and re-pumping of rubidium atoms. The isotope composition ratio for ⁸⁵Rb and ⁸⁷Rb was estimated by measuring the absorption spectrum of the rubidium vapor.
