Abstract
Die Erfindung betrifft eine Anordnung zum Beaufschlagen biologischer Strukturen mit Lichtenergie, umfassend einen eine Pumplicht und/oder eine Laserquelle (41), ein optisches Strahlformungssystem (43), einen an das Strahlformungssystem gekoppelten Lichtwellenleiter (45) zum Erzeugen eines von der durchlaufenen Leiterlänge und/oder einer Formänderung abhängenden Lichtintensitätsprofils umfassend einen Kern (46) und ein den Kern umgebendes Cladding, mit einem freien distalen Faserende. Die Anordnung zeichnet sich durch eine den Kern und das Cladding durchziehende Brechzahl - Grabenstruktur aus einer Folge konzentrischer Zonen, wobei die Zonen als eine in radialer Richtung zumindest abschnittsweise alternierende Folge aus Bereichen mit einer relativ erniedrigten Brechzahl und einer relativ erhöhten Brechzahl ausgebildet sind. Bei einem Verfahren zur Herstellung eines Lichtwellenleiters für eine Anordnung zum gezielten Beaufschlagen biologischer Strukturen mit Lichtenergie erfolgt das Erzeugen eines bezüglich der Längsrichtung des Lichtwellenleiters variablen Brechzahlprofils durch ein Bereitstellen eines Glasrohres mit einer ersten Brechzahl und Beschichten des Glasrohres mit mindestens einer eine zweite Brechzahl aufweisenden Beschichtung, ein Ziehen des beschichteten Glasrohres zum Erzeugen einer Kapillare, und ein Kollabieren der Kapillare innerhalb eines bestimmten Bereiches und innerhalb einer bestimmten Kollabierlänge zum Erzeugen eines kollabierten Abschnittes.
