| Abstract: | We propose an idea of fast cutting a display glass plate where the sample is pre-processed micromachining single shot rear-surface
and internal void arrays aligned on working plane prior to glass cleaving. Single shot void morphology is investigated varying
input pulse energy, focusing depth, and scanning speed. A femtosecond laser with pulse duration of 172 fs, central wavelength
of 780 nm, and repetition rate of 1 kHz is used to fabricate voids. |
