Abstract:
An electromagnetic pumped alkali metal vapor cell system is provided. The system comprises a vapor cell and windings. The vapor cell contains alkali metal and a buffer. The windings are positioned around the vapor cell and are configured to create an electromagnet field in the vapor cell when an AC signal is applied to the windings. The electromagnetic field pumps unexcited alkali vapor into unionized D1 and D2 states.
