Forscher Qiushi Guo hat einen Miniatur-Mode-Lock-Laser auf einem nanophotonischen Chip entwickelt, wie im Journal Science veröffentlicht. Mode-Lock-Laser emittieren kurze, kohärente Lichtimpulse mit Femtosekunden-Intervallen und werden zur Erforschung schneller Phänomene in der Natur verwendet. Bisher sind Mode-Lock-Laser groß, teuer und auf den Laborgebrauch beschränkt. Das Ziel von Guo ist es, ultraschnelle Photonik zu revolutionieren, indem er chipgroße Laser herstellt, die massenproduziert und im Feld eingesetzt werden können. Seine Forschung basiert auf dünnfilmbasiertem Lithiumniobat (TFLN), einem Material, das eine effiziente Gestaltung und Kontrolle von Laserimpulsen ermöglicht. Der gezeigte Laser emittiert eine Ausgangsspitzenleistung von 0,5 Watt und kann die Wiederholfrequenzen seiner Pulse einstellen. Dieser Durchbruch könnte Auswirkungen auf Anwendungen wie präzise Sensortechnik, optische Atomuhren und tragbare Geräte zur Diagnose von Krankheiten und Analyse von Umgebungen haben.
