Abstract

The third-derivative saturation absorption spectrum (SAS) of cesium D2 line is demonstrated via the third-harmonic technique by applying the frequency modulation to an external AOM (acousto-optical modulator). By employing the frequency discrimination of the third-derivative SAS, frequency of DBR diode laser at 852nm is locked to the hyperfine component of cesium 6S1/2F = 4 ? 6P3/2F' = 4,5 . Frequency jitter of less than in 10 seconds is estimated based on the error signal after locking in the preliminary stabilization.
