Abstract

Das Lasergainmodul ist beispielsweise anwendbar in den Bereichen der Markierungs- und Beschriftungstechnik, in der Medizintechnik sowie in weiteren Bereichen. Der Erfindung liegt die Aufgabe zugrunde, ein Lasergainmodul mit einem mechanisch einfachen Aufbau bereitzustellen, welches das gleichzeitige Pumpen mehrerer Stellen innerhalb aktiver Medien ermöglicht. Das Lasergainmodul besitzt einen sehr kompakten Aufbau und bedingt keinerlei Beschränkungen an das übrige Resonatordesign. Es zeichnet sich im wesentlichen dadurch aus, dass durch mindestens ein Strahlmanipulationselement (3) mit Strahlteilereigenschaften mehrere Strahlengänge miteinander verbunden werden, in denen durch gezieltes Endpumpen eine Verstärkung der Laserstrahlung stattfindet. Fig. 1 zeigt eine schematische Darstellung eines Lasergainmoduls.
