Frequency Biases in a Cold-Atom Coherent Population Trapping Clock
Elizabeth A. Donley, Eric M. Blanshan, Francois-Xavier R. Esnault, John E. Kitching
A compact cold-atom clock based on coherent population trapping (CPT) has been developed. The clock typically demonstrates a short-term fractional frequency stability of 4x10-11/√τ limited by frequency noise on the interrogation lasers. The largest two systematic frequency shifts that can limit the clock's long-term stability are the light shift and the Doppler shift. These biases will be presented in detail.
