Lasers have been considered for space communications since their realization in 1960. However, it was soon recognized that, although the laser had potential for the transfer of data at extremely high rates, specific advancements were needed in component performance and systems engineering, particularly for space-qualified hardware. Advances in system architecture, data formatting, and component technology over the past three decades have made laser communications in space not only a viable but also a attractive approach to intersate ....etc

Laser communications offer a viable alternative to RF communications for inter satellite links and other applications where high-performance links are a necessity. High data rate, small antenna size, narrow beam divergence, and a narrow field of view are characteristics of laser communications that offer a number of potential advantages for system design.

Transparent and conductive ZnO:Al films deposited by large area reactive
magnetron sputtering
Abstract
A new coating technology has been developed for large area deposition of transparent and conductive ZnO:Al films. ReactiveAC magnetron sputtering from metallic Zn:Al has been performed at low substrate temperature below 200 8C using the newCleanMag technology of applied films based on moving magnets for layers with low defect density and with conventional reactiveAC magnetron sputtering using static magnets (Applied Films TwinMag). ....etc
