Optical Detection of Narrow Rb87 Hyperfine Absorption Lines
Peter Bender, Earl C. Beaty, A. R.
Optical detection of the ground state hyperfine transition has been reported for sodium vapor and for cesium vapor. The collisional narrowing technique suggested by Dicke was used to reduce the Doppler width, Results are reported for Rb/sup 87/ vapor using a different optical pumping method. Absorption lines narrower, by a factor 300, than the normal Doppler width were achieved. The experimental arrangement is described. (W.D.M.)
