An improved short-arc gas discharge lamp having a solid ceramic body with an integral reflector surface. The lamp includes a sapphire window, fitted to one end of the ceramic body, and a thermally and electrically conductive base fitted to the opposite end of the ceramic cylinder to form a sealed pressure chamber. The window is secured to a unitary U-shaped flange for improved strength and leak resistance. A pair of annular back-up rings secure the window flange to the ceramic body so as to relieve stress on the window flange. The reflective surface is formed by pressing the ceramic body, when hot, with an unpolished mandrel, for greater accuracy in surface configuration. A smooth, highly reflective surface is obtained by subsequent surface treatment.
