18 January 2007 Laser-induced bulk damage in Yb:S-FAP crystals
Author Affiliations +
The Mercury laser uses ytterbium-doped strontium fluorapatite (Yb:S-FAP) crystals as the gain medium with a nominal clear aperture of 4 x 6 cm. Recent damage test data have indicated the existence of bulk precursors in Yb:S-FAP that initiate damage starting at approximately 10 J/cm2 at 9 ns under 1064 nm irradiation. In this paper, we report on preliminary results on bulk damage studies on Yb:S-FAP crystals.
