studies were conducted to determine the effect of lapping and polishing variables on fiber optic surface finish, flatness, perpendicularity to axis, and subsurface characteristics. the studies were done with a fiber having a 400 (mu)m diameter fused silica core and a 440 (mu) outer diameter fused silica cladding used for doi (direct optical initiation) system developmental work. on fibers polished to the best level of surface finish, laser-induced damage studies conducted at sandia national laboratory (snl) showed that seventy percent of the fibers passed optical power densities in excess of 5 gw/cm(sup 2), without surface damage. the geometry of two fiber optic-connector pairs mated along a common axis in an adapter was investigated to determine the tolerances necessary to achieve a desired degree of angular and positional alignment of the mating fiber surfaces
