A ceramic structure is described for use as a laser pump cavity to surround a rod of laser material and a light source emitting radiation within a range of 0.4 to 2.0 microns, and wherein laser radiation at a lasing wavelength is produced by the laser material upon exposure to the light source, the ceramic structure comprising a ceramic body having an interior surface defining the pump cavity wherein the ceramic body comprises sintered alumina having grain sizes of between about 0.3 to 0.5 microns and a packing density between about 70 to 87 percent such that the grain size and the packing density provide optimum diffuse reflectance of the radiation within the pump cavity.
