Optical radiation reflective surfaces are described for use in an unstable resonator laser system in which the output beam of the system does not contain an aperture in the middle of the beam thereby avoiding the requirement of a collimation lens system to obtain a beam of minimum divergence. The system provides a output beam which does not have a central hole.
