Abstract

In this report, we present our work towards the development of strontium based optical lattice clock testbed system [1]. This system facilitates the accomplishment of a compact and transportable strontium-based optical atomic clock (one of the two goals of iqClock project [2]) built from the components developed by our industrial partners. The testbed system allows us to benchmark and access the performance of industrial components and subsystems. With this task completed, we have been extending the testbed system to constitute a fully-fledged optical lattice clock. The main results from testbed system includes: - 1) Two stage laser cooling of ⁸⁸Sr atoms, 2) Stabilisation of 689 nm laser to ULE cavity for second stage cooling, 3) Trapping ⁸⁸Sr atoms in optical lattice trap.
