Description:
Author(s): D. R. Gozzard, S. W. Schediwy, B. Stone, M. Messineo, and M. Tobar High-precision optical frequency transfer through free-space links will enable advances in fields ranging from coherent optical communication and satellite Doppler ranging, to tests of general relativity and fundamental physics. Previous work has focused on two-way time and frequency transfer techniques using optical frequency combs. Here the authors show that a continuous-wave coherent link can exceed the fractional frequency stability of frequency-comb methods by an order of magnitude. They also highlight and discuss the technical hurdles to implementing similar links over the distances required to reach low Earth orbit. [Phys. Rev. Applied 10, 024046] Published Wed Aug 29, 2018
