Abstract

A full-operated and turn-key clock laser is based on a compact Fabry Perot cavity is developed for the Yb ion clock. The cavity is disk shape with 2 inch diameter and 9.3 mm thickness. Though the compact size, the cavity features vibration insensitive design allowing vibration sensitivity on 10-10/g level. The cavity is installed in a two-layer thermal shield with 10 hours time constant which dramatically suppresses room temperature impact on the cavity. By optimizing the vibration and temperature induced noise, the frequency stability of the laser referenced to this cavity is measured at 2×10-14, mainly limited by the cavity thermal noise.
