Abstract
The time transfer by laser link experiment T2L2 aims for a precision of 60 ps, which could be degraded by the atmospheric turbulence because of the strong variations of the photon number received by the satellite detector, from a measurement to another. The light intensity fluctuations in the satellite plane are estimated for the planned situation for which the beam radius at the atmosphere exit is significantly larger than the coherence length. Such speckle-type fluctuations are experimentally studied.
