Abstract :
Two 674-nm optical frequency standards based on the 2S1/2 - 2D5/2 transition in 88Sr+ are under development at NPL. Comparison of the standards allows determination of the frequency stability and reproducibility via difference frequency measurements. A relative frequency stability between the traps of ap3times10-15 over a 100 s averaging time has been observed. A compact, transportable system is also being developed, which could find application in ground stations or as an optical frequency clock in space.
