TY - JOUR AU1 - Dong-Hai Yang , Dong-Hai Yang AU2 - Yi-Qiu Wang , Yi-Qiu Wang AB - In this paper the long-term continuous operation for more than two months of an optically pumped cesium beam frequency standard is described, and the frequency stability for one day of 2×10-13/ day has been obtained for the first time for such a frequency standard. This was achieved by applying digital auxiliary locking loop (DALL) devices for the frequency and temperature controllers of laser diodes, and also by using sharp-angle incidence of the probing laser beam.
