Abstract

The invention is directed to a highly stable CO.sub.2 waveguide laser wherein a resonator block is used which is made of a material having a low thermal expansion coefficient. The resonator block includes a window which is transparent for the wavelength of the laser. Laser reflectors are provided which are mounted by wringing to the resonator body and define a vacuum-tight seal of the resonator body. In this way, the resonator block has a permanently defined adjustment.
