The frequency stability of a high finesse reference cavity was transferred to the entire femtosecond comb using a single error signal from the cavity. The signal was sent through a loop filter and fed back to a piezoelectric transducer attached to an end mirror of the laser for the control of the laser cavity length. The beat signals were characterized in terms of the resulting linewidth and the frequency stability. Using an independent stable continuous wave laser, it was verified that the linewidth and stability of the optical comb components, reach below 300 Hz and 5×10 -14 at 1 s averaging time.
