Figure 10.

Illustration of a too short (a) and an appropriate (b) interpulse distance in the laser ablation of metals in liquids. The diagram in (c) demonstrates relative effects of different laser pulse durations on the dependence of the productivity on the inter-pulse distance. 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 arrow and the less dense line style indicate the effect of a longer laser pulse duration on productivity. Reprinted with permission from [66].
