In order to improve an electrically excited, diffusion-cooled laser system comprising two wall surfaces slightly spaced from one another and forming an optical waveguide, the width of the wall surfaces being a multiple of the space between them and the surfaces enclosing between them a flow-free discharge chamber, and also comprising an optically unstable resonator having a resonator beam path travelling through at least part of the discharge chamber and extending lengthwise of a resonator axis as well as having an expansion transverse to the resonator axis extending as far as at least one laser beam exiting from the resonator, this transverse expansion extending transversely to a longitudinal direction of said waveguide and approximately parallel to said wall surfaces, such that the waveguide can be constructed with as large a surface area as possible without losing the beam quality of the beam exiting the waveguide, it is suggested that the resonator be followed by a laser amplifier, the amplifier beam path thereof travelling through an additional part of said discharge chamber.
