  • Author: Kurt Vogel, Judith Olson ColdQuanta, Chris Oates
Vescent Photonics, ColdQuanta, and the National Institute of Standards and Technology propose to develop a calcium-beam-based optical clock that has a viable pathway for near-term space qualification and can provide the frequency stability performance required to support precision metrology for tests of fundamental physics, worldwide timing distribution, and precision geodesy. Since time/frequency metrology offers the most precise physical measurement capabilities, ultrastable atomic clocks positioned in the near-perturbation-free environment of an earth orbit have been proposed as unique tools for performing stringent tests of General Relativity and searches for Dark Matter/Energy
