Abstract
An optical atomic clock utilizing two different laser light sources is described. A source laser is locked to a first optical resonator, which supports a whispering gallery mode for the source laser and generates optical hyperparametric sidebands from the source laser output by multi-wave mixing. A reference laser is locked to an atomic reference via a second optical resonator, and the first optical resonator is locked to the reference laser. Optical parametric sidebands, which are locked to an atomic reference but are generated from a wavelength unrelated to the clock transition of the atomic reference, are coupled out of the first optical resonator to generate an RF signal useful in atomic timekeeping.
