WebJul 21, 2024 · Optical clock progress would focus more on reducing the SWaP to reduce mission costs, while increasing the robustness of the physics package and supporting subsystems for long-term remote operation. For time transfer, it will be critical to extend existing time/frequency transfer techniques to satellite-relevant distances and velocities; … WebOptical lattice clocks are predicted to surpass the present microwave atomic clock performaces both in terms of accuracy and frequency stability. The conceptual scheme of a Sr-based optical lattice clock is the following: cold Sr atoms trapped in an optical lattice are interrogated by a pre-stabilized laser beam (the "local oscillator") on the ...
