Probing impulsive strain propagation with X-ray pulses.
Phys Rev Lett 86:14 (2001) 3072-3075
Abstract:
Pump-probe time-resolved x-ray diffraction of allowed and nearly forbidden reflections in InSb is used to follow the propagation of a coherent acoustic pulse generated by ultrafast laser excitation. The surface and bulk components of the strain could be simultaneously measured due to the large x-ray penetration depth. Comparison of the experimental data with dynamical diffraction simulations suggests that the conventional model for impulsively generated strain underestimates the partitioning of energy into coherent modes.Anomalous response of silicon to unixial shock compression on nanosecond timescales
