Handelsübliche Laserdioden erzeugen gepulste Terahertzstrahlen

(PresseBox) (Marburg, )
Marburger und Braunschweiger Physiker haben einen Durchbruch in der Terahertz-Spektroskopie erzielt. Wie Maik Scheller und Professor Dr. Martin Koch im Online-Fachmagazin "Optics Express" zeigen, lassen sich technisch nutzbare Terahertz-Signale mittels Laserdioden erzeugen, die im Vergleich zu hochwertigen Femtosekundenlasern so gut wie nichts kosten.

"Mit der neuen Methode sollte ein Terahertz-Spektrometer für jedermann erschwinglich werden", sagt der Marburger Halbleiterphysiker Martin Koch voraus, der als Seniorautor der Veröffentlichung firmiert; "auch der Einzug der Terahertz-Technologie in industrielle Anwendungen dürfte sich damit erheblich beschleunigen." Terahertzstrahlen, deren Frequenzen zwischen denen von Mikrowellen und des infraroten Lichtes liegen, gelten als letzte Domäne des elektromagnetischen Spektrums, die ughqhfevm qrdu ththrq kucuidktnegmo ere.
