Sci. Instrum.2017STABILITY; STANDARDREORTSOM21743By alternatively operating two pulsed optically pumped (POP) atomic clocks, the dead time in a single clock can be eliminated, and the local oscillator can be discriminated continuously. A POP atomic clock with a zerodeadtime (ZDT) method is then insensitive to the microwave phase noise. From tau = 0.01 to 1 s, the Allan deviation of the ZDTPOP clock is reduced as nearly tau(1), which is significantly faster than tau(1/2) of a conventional clock. During 140 s, the Allan deviation returns to tau(1/2). Moreover, the frequency stability of the ZDTPOP clock is improved by one order of magnitude compared with that of the conventional POP clock. We also analyze the main factors that limit the shortterm frequency stability of the POP atomic clock.
