Abstract
In order to improve a laser amplifying system comprising a solid-state member having a laser-active medium, a radiation field system determined by an optical guide means for the radiation field and an actively switchable, optical switching element arranged in the radiation field system for influencing the losses in the radiation field system in such a manner that this is suitable for low-amplification laser-active media, it is suggested that the solid-state member be designed like a thin plate, the radiation field system comprise an incoming branch and an outgoing branch which are coupled to one another, on the one hand, and between which, on the other hand, an amplifying radiation field is provided which is formed from a plurality of intermediate branches which extend between two optical beam reversing elements and, for their part, all penetrate the solid-state member in a direction transverse to its flat sides and within an active volume area, and that the active volume area have in directions transverse to beam axes of the intermediate branches an extension which corresponds at the most to three times the average extension of the radiation field cross sections of the volume sect…
