On signatures of sonic wavepackets in time-resolved X-ray diffractometry of metal single crystals absorbing pulse from ultrafast laser

Oleg Korovyanko, Oleksandra Korovyanko

Copper (Cu), gold (Au) (111) crystals were illuminated with 120 fs pulses and probed by 600 fs X-ray pulses. Rocking curves were measured versus 267 nm (UV) pump- 0.154 nm probe de…
