Strontium Optical Atomic Clocks in KL FAMO Blue Detuned Lattice for Strontium Atoms and Project of a Continuous Active Optical Clock with Cold Strontium Atoms

We would like to report on a design of new type of optical atomic clock - a continuous active clock with cold strontium atoms, as well as on progress with lattice clocks in KL FAMO. The active clock design will use blue detuned optical lattice to provide the Lamb-Dicke regime in the optical cavity, where conditions for superradiance emission on the clock transition will be meet. Studies of the blue detuned magic wavelength for
⁸⁸
Sr will be presented together with possibility to create a state dependence, blue detuned optical lattice.
