Ultrafast movies of atomic motion with femtosecond laser-based x-rays
Using ultrafast x-ray diffraction from a laser-plasma x-ray source, we have observed coherent phonon generation and propagation in bulk(111)-GaAs, (111)-Ge, and thin (Ill)-Ge-on-Si films. At higher optical pump fluences, ultrafast melting of Ge films is observed.
