Abstract

Frequency-stabilized and spectral-linewidth-narrowed laser diode systems are being developed for optical pumping of a cesium atomic clock. Frequency stabilization and reduction of spectral linewidth were carried out by utilizing optical feedback from a Fabry-Perot interferometer. Saturation absorption and fluorescence spectroscopy results are presented. It is shown that the long-term stability of optical locking is not sufficient for a practical atomic clock.<>
