Article on continuous optical frequency standard

Amsterdam and UMK will combine the beam preparation scheme from Tasks 44 and 53 with the UMK superradiant laser scheme from Task 54 into one true continuous optical frequency standard using the Sr 1S03P0 clock line TUW with UIBK will help with interpretation of the data and further optimization of operational parameters We will ship the vacuum chamber build in Task 52 to Torun and perform this experiment there which will give us access to stateoftheart Sr clocks as benchmarking references NKT Photonics will develop the required lownoise reference laser source
