Time-dependent photothermal characterization on damage of fused silica induced by pulsed 355-nm laser with high repetition rate
SEM images of the exit surface of fused silica sample when the visible damage is observed at (a) 6 min after irradiation by 5-W high-frequency 355-nm laser, and (b) 80 s after irradiation by 5.3-W high-frequency 355-nm laser.
