Laser communications (Lasercomm) systems have gained increasing interest for both defense and commercial applications due to their ability to provide secure, long-distance, high-bandwidth communications on the move, without the need for RF spectrum management. This paper will present field test results from …

We demonstrate real-time, femtosecond-level clock synchronization across a low-lying, strongly turbulent, 12-km horizontal air path by optical two-way time transfer. For this long horizontal free-space path, the integrated turbulence extends well into the strong turbulence regime corresponding to multiple scattering with a …

Optical time and frequency transfer offers extremely high precision wireless synchronization across multiple platforms for untethered distributed systems. While large apertures provide antenna gain for wireless systems which leads to robust link budgets and operation over increased distance, turbulence disrupts the beam …

In recent years, various terrestrial free-space optical (FSO) communications systems have been demonstrated to achieve high-bandwidth communications between mobile platforms. The terminal architectures fall into three general categories: (1) single aperture systems with tip/tilt control, (2) multi-aperture system with tip/tilt control, and …

We demonstrate synchronization of two clocks to within femtoseconds across a 12 km air path over three days. We demonstrate adaptive-optics terminals can be used for improved link availability without degradation of the synchronization performance.
