Abstract

In order to improve a laser amplifying system, comprising a solid-state member which has flat sides located opposite one another, is of a plate-like design and comprises a laser-active medium, a laser radiation field passing through the solid-state member, a pumping radiation field pumping the laser-active material, a cooling device which absorbs heat from the solid-state member via a first flat side by means of a fluid cooling medium flowing in it, and a reflector for the laser radiation field arranged on the first flat side, of the generic type in such a manner that the solid-state member may be arranged and aligned in as optimum a manner as possible it is suggested that a support with a stable shape be provided for the solid-state member, this support having the laser radiation field passing through it and being transparent for it, that the solid-state member be supported areally on a support surface of the support with a stable shape with its second flat side and be arranged so as to be defined in its shape and position essentially only via the support surface interacting with the second flat side.
