| Program | Today the definition of the SI second - and thus also official time scales such as UTC - are based on atomic units. Atomic frequency standards (or atomic clocks) realizing this principle have become indispensable parts of several of our civilisation’s modern technologies, such as e.g. high-speed telecommunication networks or satellite navigation systems. After a short introduction on atomic clocks, this presentation will discuss the principles of laser-microwave double- resonance spectroscopy in Rb vapour cells and its application to the realisation of novel types of compact Rb atomic clocks, as pursued in our group at Laboratoire Temps-Fréquence at University of Neuchâtel. Recent developments on high- performance Rb atomic clocks reaching nanosecond-level stability over one-day timescales will be presented, which are of interest e.g. for application in next generation satellite navigation systems. Work towards miniaturized Rb atomic clocks with the potential to maintain microsecond timing accuracy over several hours from a few cm3 size package will also be discussed. Such miniaturized clocks are of interest for emerging applications in network synchronization or mobile applications. | |
