    • Figure 3(c) shows the CARS signal from this layer disappears in <1 ns. The CARS signal is proportional to the square of the number of dye molecules in the probed volume (Ref. 19). To eliminate the dye background by an order of magnitude, the ablation plume from an initial volume 100 μm diam by 3 μm thick, must move a few tens of μm in < 1 ns. This requires a seemingly high velocity of >Mach 30, which turns out to be quite a bit less that what has been observed in prior experiments on PMMA ablation using picosecond pulses [e.g., T. Zyung, H. Kim, J. C. Postlewaite, and D. D. Dlott, J. Appl. Phys. 65, 4548 (1989)].

    • note
    • 6 CARS line shape is homogeneously broadened at low temperatures (T<200 K), and the linewidth increases with increasing temperature (Ref. 32). At higher temperatures, the line shape may also develop some inhomogeneous broadening, due to vibron localization (Ref. 32). In the present work, however, the term "inhomogeneous broadening" should be taken to mean only those broadening effects that are solely a consequence of pressure or temperature distributions in the sample.
