ABSTRACT:
A ceramic pump cavity structure for use in solid state lasers wherein the pump cavity comprises sintered alumina having grain sizes of between about 0.3 to 0.5 microns. Sintered alumina pump cavities having grain sizes within this range provide desirable diffuse reflectivity comparable to barium sulfate while at the same time providing a structurally strong cavity which is resistant to cracking and breakage. Combinations of the alumina oxide pump cavity with parasitic light absorbers such as samarium oxide are also disclosed.
