Snapshots of stress waves emission in a 40 µm-thick diamond plate upon a single-pulse laser of 20 µm waist-size at various times: (A,a) 0.1 ns; (B,b) 0.5 ns; (C,c) 1 ns; (D,d) 2 ns; (E,e) 3 ns. In the left-hand column (A)–(E), the 3D profiles show the field of velocity component vz, and the color code indicates the field of strain component ɛzz. In the right-hand column (a)–(e), the 3D profiles show the field of velocity component vr, and the color code indicates the field of strain component ɛrr. |
