Coherent free-space optical transmission through the atmosphere

The University of Western Australia (UWA) has developed an active stabilization system that can perform coherent free-space optical transmission through the turbulent atmosphere at stabilities better than the World’s best optical atomic clocks.

Together with two French teams, the Australian researchers tested the system over a 265 m free-space in Toulouse.

They demonstrated coherent optical transmission through the atmosphere with residual frequency instabilities below state-of-the-art optical atomic clocks.
