| Research Abstract |
Permanentally densified borosilicate glass was successfully prepared both by Deep UV laser irradiation and by application of compressive or tensile stress. The structural change of the UV-irradiated glass was investigated by micro Raman spectroscopy. Theobtained structurewassimilar tothat ofthedensified glass under a sharp diamond indenter. It was also found that the glass structures under a tensile stress can befrozen-inby DeepUVlaser irradiation.
