We present first results on a laser-pumped, double resonance (DR) Rubidium atomic clock, based on microfabricated Rb vapour cells. The study aims towards a miniature atomic clock [1] based on DR, using a lowpower laser as pump light source and a miniaturized microwave coupling structure (that will replace the bulky microwave cavity employed in today’s much bigger Rb clocks). Good signal amplitude, low background light level, and no need for GHz laser modulation are among the advantages of this approach.
