Abstract :
Advances in laser cooling of alkaline earth atoms have reduced trapped atom temperatures from the millikelvin to the microkelvin regime. Using such atoms, our optical atomic clock should have a fractional frequency uncertainty approaching 1 /spl times/ 10/sup -15/. Sub-recoil cooling and two-pulse atom interferometry are also discussed.
