Figure 2

Elastic dynamics on SLs terminated by tungsten wedges. (a) Time-dependent reflectivity (background subtracted), obtained at different locations on SL1, and thereby at different W thicknesses, and (b) corresponding Fourier power spectra. (c) Power spectra, determined from reflectivity measurement from SL 2. (d–f) Show further analysis of the dynamics found on SL 1. (d) Dependence of peak power, (e) central peak frequency, and (f) life time on the tungsten layer thickness.
