Abstract
Die Erfindung betrifft eine Lasereinrichtung (26) zur Erzeugung von Laserimpulsen (24), wobei die Lasereinrichtung (26) einen laseraktiven Festkörper (44) mit einem Güteschalter (46) und Lichtleitermittel (28) zum Einkoppeln von Pumpstrahlung (60) in den laseraktiven Festkörper (44) aufweist, und wobei eine Fokussieroptik (30) zur Fokussierung der Pumpstrahlung (60) zwischen den Lichtleitermitteln (28) und dem laseraktiven Festkörper (44) angeordnet ist. Erfindungsgemäß ist ein erster Abstand (a1) zwischen der Fokussieroptik (30) und einer Auskoppelfläche (28a) der Lichtleitermittel (28), durch die die Pumpstrahlung (60) von den Lichtleitermitteln (28) auf die Fokussieroptik (30) abstrahlbar ist, verstellbar, und ein zweiter Abstand (b1) zwischen der Fokussieroptik (30) und dem laseraktiven Festkörper (44) ist verstellbar.
