Miniaturized optical system for atomic fountain clock

doi:10.1088/1674-1056/20/6/063201

Abstract Using modularized components, we have built a miniaturized optical system for ⁸⁷Rb atomic fountain clock that is fitted on an 80 cm×60 cm optical breadboard. Compared with the conventional optical setup on the table, our system is more compact, more robust and miniaturized. Taking advantage of this system, laser beams are transmitted through eight optical fibre patch cords from the optical breadboard to an ultra high vacuum system. This optical setup has operated for five months in our fountain system and required no alignment.
