An evacuated chamber utilizing an arrangement of three mirrors for accurately focussing a large diameter, high power pulsed laser beam or continuous wave laser beam either in a small focal volume or onto the surface of a target placed inside the chamber is described. The invention enables the production of an intense photon distribution within a center-of-momentum region or the uniform irradiation of laser fusion pellets.
