Figure 2.

Different damage patterns and characteristic dimensions of the trough produced in water by 100 pulses (0.2 J and 20 Hz) during scanning treatment at various fiber speeds (v_fiber). (a) Damage craters produced by the stationary fiber (v_fiber = 0 mm/s) and one-fifth of the damage troughs created at different v_fiber under SD = 0.10, 0.25, and 0.50 mm (scale bar = 0.5 mm), (b) mean trough width (${\overline{W}}_m$) (small circles in different colors) and total trough length (L_trough) (small purple triangles), (c) mean trough depth (${\overline{D}}_m$), (d) surface profile area (A_{s, profile}), and (e) trough volume (V_trough) quantified by OCT imaging analysis and plotted vs. v_fiber.
