Ramsey signals with a narrow central fringe width of 1.5 kHz combined with a competitive contrast of > 5 % are observed, resulting in a clock short-term stability of approximate to 1x10(-11) tau(-1/2). The employed pulsed optical pumping (POP) scheme bears promise for reduced light-shift effects and thus for improved clock stability on medium- to long-term timescales.Automation & Control SystemsComputer Science, Information SystemsEngineering, Electrical & ElectronicAutomation & Control SystemsComputer ScienceEngineeringatomic clockramsey interrogationpulsed optical pumpingdouble resonancerubidiummicrofabricationvapor celltext::conference output::conference proceedings::conference paper
