    Abstract: A steerable laser transmitter uses a two-stage architecture for beam steering. A LCWG is used to provide continuous fine steering and a PG stack is used to provide discrete coarse steering. An optical amplifier is inserted between the LCWG and the PG stack to provide gain and increase transmitter power, hence range. The LCWG is configured to limit its steering range to the acceptance angle of the optical amplifier, at most ±2°×±2°. The result is a high-power laser transmitter that can be rapidly and precisely steered over a large FOR.

    Abstract: A system includes a network having multiple network nodes each configured for free-space optical communication. Each network node includes one or more apertures through which optical beams are transmitted and received over optical links. The optical links include (i) a traffic link that transports higher-rate traffic between nodes and (ii) an acquisition/tracking link that transports lower-rate signals used to establish and maintain location knowledge of other nodes. Each network node also includes a network processor configured to determine one or more backup paths through the network. Each network node further includes a beam steering unit configured to redirect an optical beam from the traffic link onto the acquisition/tracking link to create a backup traffic link.

In one example a beam director includes a pre-director configured to steer an optical beam over a first field of regard, and a beam angle magnifier that includes a beam directing apparatus and a field-of-regard switch, the beam angle magnifier configured to expand the first field of regard to a second field of regard larger than the first field of regard, wherein the beam directing apparatus is configured to receive the optical beam from the pre-director and to alter a pointing direction of the optical beam, and the field-of-regard switch configured to receive the optical beam from the beam directing apparatus, and to direct the optical beam into one of first and second bands of coverage within the second field of regard. The beam angle magnifier may be disposed within a rotatable housing.
