Laser induced transient structures in a 150 nm gold crystal Academic Article

abstract

• The evolution of transient structures induced in gold crystals by irradiation with 400 nm, 100 fs laser pulses has beenmeasured bymeans of time resolved x-ray diffraction. The data show that the photon/electron interaction generates a hot electron wave on a 150 nm Au crystal, which is responsible for a "blast force" that generates an intense shock wave that alters the lattice structure as it propagates, with sound velocity, through the bulk of the crystal. This mechanical force is developed within 1-2 ps after the laser pulse interacts with the gold surface electrons. Other major effects that have contributed to the strain in the lattice have also been evaluated.
