Abstract

Ein Laser mit einem Stehende -Wellen - Resonator umfasst einen ersten Resonatorabschnitt (26), der den ersten Endspiegel (24, 24') und gegebenenfalls weitere der optischen Elemente (32, 40) aufweist, die mit dem Laserstrahl zwischen dem ersten Endspiegel (24, 24') und dem Lasermedium (23) zusammenwirken, und einen zweiten Resonatorabschnitt (27), der den zweiten Endspiegel (25) und weitere der optischen Elemente (36-39) aufweist, die mit dem Laserstrahl zwischen dem Lasermedium (23) und dem zweiten Endspiegel (25) zusammenwirken. Mindestens eines der optischen Elemente (24, 40) des ersten Resonatorabschnitts (26) ist fokussierend ausgebildet. Dadurch weisen die Strahl -Achsen (30, 30') des Laserstrahls, die sich bei jeweiligen Verkippungen von zumindest einem der im zweiten Resonatorabschnitt (27) angeordneten optischen Elemente (25, 36-39) ergeben, mindestens einen Kreuzungspunkt auf. Dieser Kreuzungspunkt oder einer dieser Kreuzungspunkte der Strahl -Achsen (30, 30') des Laserstrahls liegt im Pumpbereich des Lasermediums (23) oder weist einen Abstand vom Pumpbereich auf, der weniger als die Rayleighlänge beträgt. Der Radius (w) des Laserstrahls ist zumindest über den Abschnitt des Laserstrahls, der zwischen dem Lasermedium (23) und dem nächstgelegenen fokussierenden Element (24, 40) des ersten Resonatorabschnitts (26) liegt, kleiner als das Fünffache, vorzugsweise kleiner als das Dreifache, des Radius (w) des Laserstrahls im Pumpbereich des Lasermediums (23).
