Abstract

Die vorliegende Erfindung betrifft ein Kurzpulslasersystem zur Erzeugung elektromagnetischer Pulse mit einem ersten Resonator mit einem ersten Strahlengang und einer ersten Resonatorlänge, einem zweiten Resonator mit einem zweiten Strahlengang und einer zweiten Resonatorlänge und einem Verstärkungsmedium, wobei das Verstärkungsmedium sowohl in dem ersten Strahlengang des ersten Resonators, sodass es elektromagnetische Strahlung in dem ersten Resonator verstärkt, als auch in dem zweiten Strahlengang des zweiten Resonators, sodass es elektromagnetische Strahlung in dem zweiten Resonator verstärkt, angeordnet ist. Gegenüber einem solchen System ist es Aufgabe der vorliegenden Erfindung, ein Kurzpulslasersystem sowie ein Verfahren zum Erzeugen optischer Pulse bereitzustellen, welche die Erzeugung eines ersten und eines zweiten Pulses mit einer einstellbaren zeitlichen Verzögerung mit hohen Abtastraten ermöglicht. Zur Lösung dieser Aufgabe wird vorgeschlagen, das eingangs genannte System derart weiterzuentwickeln, dass der erste Resonator so eingerichtet ist, dass er genau einen ersten Polarisationszustand der elektromagnetischen Pulse unterstützt, und der zweite Resonator so eingerichtet ist, dass er genau einen zweiten Polarisationszustand unterstützt, wobei der erste und der zweite Polarisationszustand zueinander orthogonal sind und wobei der erste und der zweite Resonator so eingerichtet sind, dass die erste und die zweite Resonatorlänge relativ zueinander veränderbar sind.
