Abstract :
Summary form only given. We demonstrate picosecond time-resolved X-ray diffraction from GaAs single crystals using a tabletop ultrafast X-ray diffractometer with a laser plasma X-ray source. Excitation of the crystal with 800-nm, 40 fs, 20Hz laser pump pulses initiates rapid lattice dynamics, which, after a variable delay time, are probed by diffracting ultrafast Cu K X-ray pulses from the (111)-planes.
