Abstract

The use of a frequency double copper vapor laser to clean micron and sub-micron sized alumina particles from glass surfaces shows that surface optical damage of various morphologies occur at sites local to individual contaminant agglomerates. Additionally, a faint ring of about half the laser beam size occurs generally. This ring is quite difficult to visualize and is more prevalent when smaller contaminant particles are used. Results of the trends of surface optical damage with laser fluence and particle size are presented as well as the results of diagnostic studies to confirm the nature of the ring damage.
