Knowledge of a laser beam's shape and output-power distribution is critical for optimizing laser performance. Neil Savage summarizes the latest beam-profiling products on the market. People using ...
The German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) operates a laser with an open beam path at its DLR Institute of Technical Physics in Lampoldshausen. Researchers at this ...
Marx suggested that if an interstellar vehicle were driven by the pressure exerted on it by a light beam transmitted from the Earth, then, because the recoil momentum and energy would now be ...
