Subsurface Damage in Optical Materials: Origin, Measurement and Removal: Summary.

摘要

The detection, measurement and removal of subsurface damage is a major effort of the LLNL Optical Sciences and Engineering Group. Three methods currently used to detect and measure the depth of damage in glasses and crystalline materials are described: taper polishing and etching, constancy of chemical etch rate, and small specimen fracture. In addition, results will be given to show that the depth of damage can often be approximated from the surface roughness and Young's modulus. 11 refs., 3 figs. (ERA citation 14:001014)
