With the availability of spectrally pure lasers and the ability to precisely measure optical frequencies, it appears the era of optical atomic clocks has begun. In one clock project at NIST we have used a single trapped Al+ ion to make a clock based on an ultraviolet transition. With single ions uncertainties in systematic effects are smallest, reaching a fractional error of Δf/f0 = 8.0 x...
