Figure 11.

Illustration of the effect of the liquid flow rate (a) and of the liquid layer height (b) on the productivity in the laser ablation of metals in liquids. The diagram in (c) demonstrates relative effects of different liquid layer heights on the dependence of the productivity on the volume flow rate. In (c), both axes scale linearly. The trends shown in the diagram represent the interpretation of the combined results of the discussed literature in Section 2.2.1. In (c), the dashed line shows the effect of lower liquid layer height on the productivity, and the dashed line shows the effect of a too low liquid layer height compared to the solid line, respectively.
