Figure 8. Dependence of the printed droplet size on laser pulse duration, pulse energy, and resulting peak power. Each color repre-
sents a different printed droplet size. The measured values are depicted as spheres; the lines represent curves fitted to the measured
values. With increasing pulse duration, the required energy increases linear (but not proportional) and the required peak power de-
creases inversely.

Figure 9. Dependence of the jet velocity on laser pulse energy and intensity. With three different focal spot sizes, the average jet
velocity was observed at different pulse energies and intensities. For low energies (and intensities), the jet velocity depends only on
the intensity and not on the pulse energy. With increasing intensity, however, pulse energy becomes more important and the jet velo-
city differs at equal intensity but different focal spot sizes and pulse energy.
