Abstract

Die vorliegende Erfindung betrifft eine Vorrichtung und ein entsprechendes Verfahren zum Erzeugen von Laserstrahlung mit geringer Bandbreite und nachfolgender effizienter Frequenzkonversion. Diese Vorrichtung umfasst folgende Bestandteile: eine Laserquelle (1), ein frequenzselektiven Element (3), ein Frequenzwandler (4-6), ein x-y Scanner (7) wobei das frequenzselektive Element (3) zwei dielektrische Schichtfolgen umfasst, die durch eine Zwischenschicht ('spacer') getrennt sind, wobei die gesamte Schichfolge auf einem transparenten Substrat aufgebracht ist. Das erfindungsgemässe Verfahren umfasst folgende Schritte: Erzeugung eines Laserstrahles; Zwingen des Lasers zur schmalbandigen Emission mittels eines einzelnen frequenzselektiven Elements (3); Abstimmung der Laserfrequenz mittels Drehung des Spektrometers (3) um eine Achse, die senkrecht zum Laserstrahl ist; Verstärkung der Frequenz mittels eines Frequenzwandlers (4-6); Fokussierung und Ablenkung der Strahlung mittels eines x-y Scanners (7).
