Optical pumping in a microfabricated Rb vapor cell using a microfabricated Rb discharge light source

Vinu Venkatraman, Songbai Kang, C. Affolderbach +2 more

Miniature (<few cm3) vapor-cell based devices using optical pumping of alkali atoms, such as atomic clocks and magnetometers, today mostly employ vertical-cavity surface-emitting lasers as pump light sources. Here, we report on the demonstration of optical pumping in a microfabricated alkali vapor resonance cell using (1) a microfabricated Rb discharge lamp light source, as well as (2) a conventional glass-blown Rb discharge lamp. The microfabricated Rb lamp cell is a dielectric barrier discharge (DBD) light source, having the same inner cell volume of around 40 mm3 as that of the resonance cell, both filled with suitable buffer gases. A miniature (∼2 cm3 volume) test setup based on the Mz magnetometer interrogation technique was used for observation of optical-radiofrequency double-resonance signals, proving the suitability of the microfabricated discharge lamp to introduce efficient optical pumping. The pumping ability of this light source was found to be comparable to or even better than that of a conventional glass-blown lamp. The reported results indicate that the micro-fabricated DBD discharge lamp has a high potential for the development of a new class of miniature atomic clocks, magnetometers, and quantum sensors.

Demonstration of optical pumping using a micro-fabricated Rb dielectric barrier discharge (DBD) lamp

Songbai Kang, Vinu Venkatraman, C. Affolderbach +2 more

Recently, a low-power, mm-scale (~0.3 cm3) Rb dielectric barrier discharge (DBD) lamp was demonstrated, in view of the development of a chip-scale atomic clock based on the traditional double-resonance (DR) interrogation scheme. Here, we report on the demonstration of optical pumping in a micro-fabricated Rb vapor cell (~0.3 cm3), using such a DBD Rb lamp as a pump light source. As a first step, we demonstrate Zeeman optical pumping in the Mz magnetometer configuration and observe the DR error signals. Comparative studies between DBD lamp and glass-blown (GB) lamp on the intensity noise and the DR error signals were performed. These results show that the performances of DBD lamp are comparable to those of a conventional glass-blown lamp, which indicates a high potential of the DBD lamp for the development of miniature atomic clocks, magnetometers and quantum sensors.
