Objectives:
1) Active clock based on superradiant lasing of Sr atoms
Task 1: Within the Quantum Flagship project iqClock, we set up an apparatus for an active optical superradiant clock with sequential loading. The DC will finalize the construction of the apparatus, including assembling an in-vacuum superradiant cavity, aligning necessary optics, and preparing ultra-cold Sr atoms in the excited 3P0 state inside a blue-detuned optical lattice co-aligned with the superradiant cavity. Task 2: The DC will improve the UMK superradiant system with procedure and electronics developed for transportable clocks within the Quantum Flagship project AQuRA and the Euramet project TOCK. This includes a new open hardware control system based on the Sinara and ARTIQ ecosystems.
2) Continuous superradiant lasing
Task 3: The DC will test continuous loading of the superradiant cavity from a source based on an optical conveyor belt made of a red-detuned lattice inside a bow-tie power build-up cavity. Task 4: The DC will test continuous loading from a source based on a hollow core fibre developed within the QuantERA project QuantumGuide. Task 5: The DC will compare the performance of the superradiant strontium clock with at least two of the three available passive clock systems: the Sr1 and Sr2 strontium optical clocks operating at UMK, and the AQuRA transportable clock.
