Comparison of analytic solution and FEM solution for displacement w and strain εzz of a one-dimensional wave at time t = 3.5 ns after photon–matter interaction and after t = 3.5 ns + 20Tround. (a) Using a temporal Gaussian profile with tp = 600 ps for the FEM simulation. (b) Considering an instantaneously temperature rise at t = 0 ns. |
