Frequency stabilization of GaAlAs laser using a Doppler-free spectrum of the Cs-D2line

Experimental results are shown on the frequency stabilization of a GaAlAs laser using a Doppler-free spectrum in the saturated absorption of the Cs-D
2
line at 852.1 nm. The frequency stability (Allan variance) between
3.0 \times 10^{-12}
and
1.0 \times 10^{11}
was obtained at the averaging time between 0.1 and 1000 s.
