Abstract
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.Proceedings Title
