Rubidium vapor-cell references based on the 5S to 6P transitions — •Julien Kluge, Aline N. Dinkelaker, and Markus Krutzik — Humboldt-Universität zu Berlin

Optical frequency standards based on spectroscopy of Rubidium vapor benefit from high component technology readiness level, allow for vapor-cell micro-integration and physics package miniaturization. In conjunction with an optical frequency comb, these standards could be advanced to compact and simple vapor-cell based clocks which have the potential to achieve fractional instabilities comparable to state-of-the-art commercial systems [1,2].
In this poster, we discuss the optical properties of Rubidium beyond the D1/D2 line and highlight two concepts we currently study for future compact references onboard small satellites. One is based on direct modulation transfer spectroscopy of the 5S→ 6P transition using GaN based diode laser operating at 420 nm, the other on spectroscopy of the two-photon transition from 5S→ 5D at 778 nm. We give an overview on system design, compare the expected performance and discuss the prospects of integrating a payload which meets the stringent size, weight and power (SWaP) requirements of a small satellite.
