A longitudinal feedback system for a storage ring free electron laser (SRFEL) has been developed at the UVSOR. Instantaneous temporal deviation of the FEL optical pulse with respect to the electron bunch is measured in the frequency domain by detecting a phase between higher harmonic components of respective revolution frequencies. The phase deviation is fed back to control the storage ring RF frequency so as to readjust the effective length of the optical cavity. Compensating for the temporal drift with the feedback system, synchronism between the FEL micropulse and the electron bunches was successfully maintained for a reasonably long time.
