Linking the laser ablation and breakdown thresholds and ablation quality at femto- and picosecond pulse durations for fused silica glass.

The damage thresholds are given by black dots (Stuart et al.¹⁵) and open triangles (Lebugle et al.¹⁹). Black rhombic symbol shows the optical breakdown threshold measured at pulse duration of 25 fs by Li et al.²⁰. At the upper panel, the SEM images of laser-produced craters are introduced from the work by Lenzner et al.¹⁷ with corresponding irradiation regimes shown by stars. Two-colour hexagons indicate the damage (bottom) and breakdown (top) thresholds measured in the present work for Corning’s Willow glass. The regimes studied in this work are shown by vertical arrow pointing up with underlining the conditions of special interest between two thresholds by ellipse.
