Abstract

We report preliminary results of the frequency stabilization of DBR-diode lasers to saturated absorption of Cs D-line by means of the modulation transfer spectroscopy method. From the experimental analysis of the signal to noise ratio, a relative frequency stability of the order of /spl ap/10/sup -12//spl middot//spl tau//sup - 1/2 / should be achieved.
