Abstract

We have set-up an experiment in order to use ultra-fast time-dependant x-ray diffraction as a diagnostic to probe laser-induced phase transitions in solids. Such studies have previously been performed using laser probes in the infra-red, visible or ultraviolet spectral range. However, in order to directly probe structures in solids, and large molecules it is necessary to use x-ray radiation. In an ongoing project at the ALS synchrotron aimed at probing structural dynamics in solids using with a sub-picosecond time we have incorporated a streak camera with a temporal jitter smaller than 2 ps. We have used this streakcamera to observe a decrease in bragg reflectivity from single crystal InSb following laser irradiation.
