Durch Photonendruck und Materialabtrag können Laser vom Erdboden aus über große Entfernungen hinweg die Bewegung eines Weltraumschrottobjekts verändern. Bereits ein leichtes Abbremsen kann Kollisionen vermeiden. Eine längere Folge von Bestrahlungen kann ein Schrottobjekt sogar beseitigen, durch Wiedereintritt in die Erdatmosphäre. Als Vorbereitung liefern spektrale Lichtkurvenanalysen detaillierte...
High energy pulses of a CO 2 laser are focused in a parabolic mirror yielding to a laser-supported detonation. The generated thrust acting on the reflector as a bell nozzle is studied in multiple pulse free flight experiments with respect to axial, lateral and angular momentum coupling. The employment of an ignition pin on the reflector's axis of symmetry lowering the ignition threshold by...
