Laser-Induced Breakdown Spectroscopy Applied on Liquid Films: Effects of the Sample Thickness and the Laser Energy on the Signal Intensity and Stability

Figure 3

Average peak intensity of C I and Al I lines from the diesel droplet, measured over 10 pulses, as a function of the rotation speed for laser energies of 23 mJ (a) and 70 mJ (b); the corresponding RSD is shown in (c) and (d), respectively.
