We demonstrate stable optical frequency transfer over a 265m free-space link, overcoming atmospheric turbulence. This breakthrough enables precise timescale comparisons for advanced scientific applications using optical atomic clocks.

Area of Science:

  • Quantum Physics
  • Metrology
  • Optical Engineering

Background:

  • Timescale comparison using optical atomic clocks offers significant scientific benefits.
  • Atmospheric turbulence degrades precision in ground-to-space and terrestrial free-space laser links.
  • Active stabilization is crucial for reliable optical frequency transfer.

Purpose of the Study:

  • To achieve phase-stabilized optical frequency transfer over a turbulent horizontal free-space link.
  • To demonstrate the capability for clock-limited frequency comparisons despite atmospheric disturbances.
  • To develop a compact, human-portable system for high-precision optical links.

Main Methods:

  • Implemented a 265m horizontal point-to-point free-space link with active tip-tilt mirrors.
