ESR7 - Autonomous frequency stabilisations in a superradiant clock- position filled
Monitoring and control systems that will allow for automatic and unattended operation of a superradiant optical clock. The laser systems used for cooling, trapping and transporting the atoms need to be locked to various frequency references by autonomous stabilisation systems with automatic mechanisms for re-locking. A similar locking solution will be applied to various optical cavities present in the system, for instance the power build-up cavities for optical lattices or the cavity required for superradiant emission. The solutions developed within this task require new hardware for automatic control and re-locking of laser and cavities systems and adjustment of optics, as well as software for automatic scheduling of procedures that currently require human intervention. The algorithms and hardware developed to improve the robustness and autonomousness of laboratory superradiant optical clocks will benefit in the future industrial partners developing compact and portable optical clocks for field applications.
ESR8 - Moving from a superradiant laser to a frequency standard position filled
A frequency standard requires the determination of a precise accuracy budget by evaluating all possible frequency shifts and their uncertainties. Creating
the accuracy budget for state-of-the-art passive optical atomic clocks follows well-known procedures, but no such procedures exist for active, superradiant
clocks. The goal of this project is to develop these procedures. Different procedures will be developed, which can be applied in case a second reference source (e.g. a passive optical atomic clock) is available or not. A continuous superradiant optical clock is under development at UvA and UMK. UMK operates two passive strontium optical lattice clocks, referenced to a femtosecond optical frequency comb synchronized to the frequency of local representations of the International Atomic Time, which provides traceability to the SI second through a 330 km-long stabilized fibre optical link. This system provides the testbed for the procedures developed by the ESR.
