Free-space laser communication systems are increasingly implemented on state of the art satellites for their high-speed connectivity. This work outlines a demonstration of the Modular, Agile, Scalable Optical Terminal (MAScOT) we have developed to su

Free-Space Laser Communications XXXI.
Free-space optical communications in space offer many benefits over established radio frequency based communication links; in particular, high beam directivity results in efficient power usage. Such a reduced power requirement is particularly appeali

Free-Space Laser Communication and Atmospheric Propagation XXX.
Delivery of large volumes of data from low-Earth orbit to ground is challenging due to the short link durations associated with direct-to-Earth links. The short ranges that are typical for such links enable high data rates with small terminals. While

Near-Earth laser communication system designs typically use the near-symmetric power levels in duplex links as bright sources upon which to base active beam stabilization. In deep space, it may be difficult to provide a constant, high-power laser bea

Summary Although there is a recognised need for routine monitoring of the exposure of operating theatre staff to waste anaesthetic gases, there is as yet no standard method for carrying out such measurements. We have assessed a commercial version of

Collisions between SF 2+ and Ar have been investigated using time-of-flight mass spectrometry over a collision energy range of 2.6–6.2 eV in the centre-of-mass frame. The formation of SF + , S + and Ar + in single electron transfer reactions has be

The Lunar Laser Communication Demonstration (LLCD) is NASA’s first demonstration of the use of free-space optical communications for high-rate duplex communications between a lunar spacecraft and an Earth ground station. The LLCD system comprised a
