Optical Breakdown in Liquid Suspensions and Its Analytical Applications

Figure 7

Fragments of interferograms of laser spark columns in ethanol. The laser pulse energy is 70 mJ. The laser beam is focused from right to left. The focal spot coincides with the picture’s left margin. (a) Delay of 152 ns (second time range); (b) delay of 333 ns (third time range). Dotted circles mark spherical shockwave fronts. Reprinted from [72], with permission from Elsevier.
