Recent developments have allowed x-ray diffraction techniques at synchrotro
n radiation facilities to be employed with a temporal resolution of around
1 ps. These developments are the availability of firstly, high brightness t
hird-generation x-ray sources, secondly, passively mode-locked lasers with
100 fs temporal duration and thirdly, averaging streak cameras with sub-pic
osecond temporal resolution. In this paper, we discuss how these novel devi
ces are combined in time-resolved x-ray diffraction experiments at synchrot
ron radiation facilities.
