Abstract An experiment of a high performance small optically pumped caesium (Cs)
beam frequency standard is reported. An extended cavity diode laser works as the probing laser, of which the frequency is stabilized by the Zeeman modulation method. The running parameters of the frequency standard are dynamically optimized via digital servo electronics. The experimental setup improves the frequency stability up to 1.8×10-12 at τ=1s and about 1.0×10-13 at τ=105s (Allan deviation).
