Abstract
We describe a system that combines a cavity-stabilized laser, a hydrogen maser and a cesium fountain clock. It provides an optical reference frequency that over the course of half a day drifts with less than 100 µHz/s. Furthermore it allows for a convenient measurement of an absolute frequency in the optical domain.
