| Abstract: | We report on the microstructure formation in Foturan
glass, induced by 1~kHz, 120 femtosecond laser irradiation. It is
found that the line-shaped filamentation, not void array tends to be
formed in this glass. This is different from our previous
experimental results in fused silica and BK7 glasses. A possible
mechanism Ag$^+$ captures the free electrons generated by laser, is
proposed to explain the observed phenomena. |
