Abstract
The invention relates to an optical amplifier arrangement for amplifying ultra-short pulsed laser radiation comprising a mode-locked laser () and two or more optical amplifiers () arranged downstream of the laser () in the propagation direction of the laser radiation. Optical amplifier arrangements of this type are known in the prior art. Here the intention is to present an alternative to the known amplifier arrangements. The invention proposes arranging between the laser () and the optical amplifiers () at least one splitting element () which splits the pulsed laser radiation between a plurality of amplifier channels (), wherein each amplifier channel () has at least one optical amplifier (), and wherein at least one common combination element () is disposed downstream of the amplifier channels () and coherently superimposes the pulsed laser radiation amplified in the amplifier channels ().
