摘要： This paper studies a miniature low power consumption laser-pumped atom vapour cell clock scheme. Pumping 87Rb with a vertical cavity surface emitting laser diode pump and locking the laser frequency on a Doppler-broadened spectral line, it records a 5× 10-11τ-1/2 (τ <500~s) frequency stability with a table-top system in a primary experiment. The study reveals that the evaluated scheme is at the level of 2.7 watts power consumption, 90~cm3 volume and 10-12τ -1/2 short-term frequency stability.

Abstract: This paper studies a miniature low power consumption laser-pumped atom vapour cell clock scheme. Pumping 87Rb with a vertical cavity surface emitting laser diode pump and locking the laser frequency on a Doppler-broadened spectral line, it records a 5× 10-11$\tau$-1/2 ($\tau$ < 500 s) frequency stability with a table-top system in a primary experiment. The study reveals that the evaluated scheme is at the level of 2.7 watts power consumption, 90 cm3 volume and 10-12$\tau$ -1/2 short-term frequency stability.

Key words: laser-pumped atom clock, laser frequency stabilization, rubidium vapour cell clock
