Abstract
In a solid-state laser amplifier including at least two laser-active media in a common laser radiation field, the laser-active media do not form a hard aperture for the laser radiation field. Each of the laser-active media define a plane that is penetrated by the laser radiation field. The laser amplifier includes at least one focusing optical element disposed in the laser radiation field between two adjacent laser-active media. A focal length and a distance of the focusing optical element from the planes of the two adjacent laser-active media are selected such that the planes of the laser-active media are approximately mapped onto each other by a near-field far-field transformation.
