Study of Multiple Optical Transitions in Rb Using Laser Diodes

C.L.J. Newton, H.G. Robinson

Abstract:	Recent work with laser diodes has indicated their potential usefulness in optically pumping atomic frequency Standards. We consider various optical pumping schemes for Rb incorporating such light sources at two Di frequencies for experimental situations of either evacuated wall-coated cells or atomic beams. Numerical integration of rate equations governing the level populations with arbitrary pumping light choices of intensity, D1 hyperfine transition(s), and polarization and subsequent calculation of scattered light provide a simplified 0-0 hyperfine signal analysis. By frequency modulating one laser diode, we have excited two optical transitions in an evacuated wall-coated cell and observed a large hf signal.
