Point-to-Point Stabilised Optical Frequency Transfer with Active Optics
Benjamin P. Dix-Matthews,Sascha Schediwy,David R. Gozzard,Etienne Savalle,Francois-Xavier Esnault,Thomas Leveque,Charles Gravestock,Darlene D’Mello,Skevos F. E. Karpathakis,Michael E. Tobar,Peter Wolf +10 more
TL;DR: In this paper, the authors demonstrate phase stabilized optical frequency transfer over a 265 m horizontal point-to-point free-space link between optical terminals with active tip-tilt mirrors to suppress beam wander, in a compact, human-portable setup.
