Frequency stabilization of DBR diode laser against Cs absorption lines at 852 nm using the modulation transfer method

Fire report the preliminary results on 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 obtained signal to noise ratio a relative frequency stability in the order of approximate to 10(-12.)tau(-1/2) should be achieved.
