Kapah (2023): A Two-Decade Laser Refinement Technology for Ultra-Pure Terahertz Waves
Researchers at the Laboratoire Interdisciplinaire de Physique (LIPhy) have developed and refined a laser spectral narrowing technology over nearly 20 years. The core technique, known as optical feedback, enables the generation of exceptionally pure terahertz (THz) waves. This is achieved through the optical heterodyning, or photo-mixing, of two low-phase-noise lasers. The process results in highly stable and precise THz radiation, a advancement with significant potential for applications in spectroscopy, imaging, and communications where signal purity and stability are critical.
Le LIPhy a développé une technologie de rétroaction optique affinant les lasers depuis près de 20 ans, permettant de générer des ondes térahertz très pures via le photo-mixage de deux lasers à bas bruit de phase. Cette avancée impacte les domaines nécessitant des sources THz de haute précision, comme la spectroscopie ou l'imagerie.
