Abstract

In order to provide a laser amplification system comprising several solid-state volumes having a laser-active medium, a pumping radiation source, a pumping radiation reflector which allows a leg of the pumping radiation field entering the solid-state volume to pass through the solid-state volume again as outgoing leg such that the incoming leg and the outgoing leg form a first pumping branch, a first pumping radiation path, in which the pumping radiation field passes through the first pumping branches in a first sequence, with which the individual solid-state volumes are acted upon with pumping power as uniformly as possible, it is suggested that each solid-state volume be penetrated by a second pumping branch, the incoming leg of which and the outgoing leg of which are located in a second plane different to the first plane, that a second pumping radiation path be provided, in which the pumping radiation field passes through the second pumping branches in a second sequence and that in the second sequence the order of the solid-state volumes be changed in relation to the first sequence.
