  • Patent number: 6577666
    Abstract: In order to improve a laser amplification system, comprising a solid-state body having a laser-active medium, a pumping radiation source for generating a pumping radiation field which passes through the solid-state body several times, an optical pumping radiation imaging means which is arranged between the pumping radiation source and the solid-state body and focuses a leg of the pumping radiation field entering the solid-state body onto the solid-state body and at least one optical refocusing means which focuses a leg of the pumping radiation field exiting from the solid-state body onto the solid-state body again in the form of a leg entering the solid-state body and different to the outgoing leg, in such a manner that as high a pumping radiation power density as possible can be generated in the solid-state body with as little resources as possible it is suggested that the optical refocusing means reshape the leg exiting from the solid-state body into an intermediately collimated leg and reshape the intermed

  • Patent number: 6438152
    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
