    Abstract

    Preliminary laser exposure tests of uncoated, polished titanium-doped sapphire from Union Carbide Corporation are reported. The measured surface damage thresholds varied from ∼3 to ∼14 J/cm2, depending on surface finish and sample orientation. The dependence on orientation is not correlated with crystallographic direction. A strong dependence on doping level was not observed. Well polished samples failed by pitting of the surface. On one sample, internal damage was also observed at fluences as low as 7 J/cm2.
