Figure 5
(a) Bi (111) Bragg peak shift (black dots) and fit (blue line). The red curve is the derivative (in arbitrary units) of the fit. Inset (b) shows the response on a 1000 ns and (c) on a 2 ns time scales. The bismuth sample was excited by a 1030 nm, 12 ps laser pulse with a fluence of 182.4 µJ cm−2. Raw detector images are shown in (d) before and (e) after the laser pulse with the integrated intensity profiles before (blue) and after (orange) shown in (f). |
