Abstract
Surface incandescence properties of proton implanted fused silica have been researched with a focused CO2 laser. We have discovered that in the initial stage of incandescence a thermoluminescent peak appears. We call it blackbody thermoluminescence. In our silica samples, with a 100 micron spatial resolution, the blackbody thermoluminescence mapping reveals surface and sub surfaces defects made by the polishing process. We show how laser damage and laser conditioning are the same two facets of this blackbody thermoluminescence occurrence.
