Abstract
The invention relates to a laser amplifier system consisting of a solid body, which comprises a laser-active medium, of an excitation source for producing an excited state of the laser-active medium, and of an amplifier radiation field, which repeatedly permeates the solid body and out of which a laser beam can be decoupled. The aim of the invention is to improve a laser-amplifier system of this type so that the highest number of passages of the amplifier radiation field through the solid body can be attained using optical means that are provided in the most simple possible form. To this end, the invention provides radiation field guiding optics which enable the amplifier radiation field to enter the solid body in the form of a number of incident branches with locally different trajectories, and which enable the amplifier radiation field to exit the solid body in the form of at least one emerging branch with a trajectory that differs locally from those of the incident branches. In addition, the radiation field guiding optics comprise at least one deviating unit which, out of at least one of the branches emerging from the solid body, forms a branch which enters the solid body and wh…
