We present a method to continuously tune the degree of spatial coherence of a short-wavelength laser. The method is based on the optical properties of the hollow-waveguide Fabry-Perot resonators with external mirrors. The potential of the technique is demonstrated experimentally on a capillary nitrogen laser (Λ = 337.1 nm). The results of the work can be used for the construction of short-wavelenth lasers with tunable spatial coherence.
