Investigation of structural dynamics of substances using ultrafast electron diffraction and microscopy

Abstract: The structural dynamics of matter induced by powerful and most often femtosecond laser pulses is manifested in an atomic-molecular “movie”, a collection of processes the exploration of which is of immense interest for modern natural science. Studying this global phenomenon requires an ultra-high spatiotemporal resolution that involves the development of dedicated research methods. Laser spectroscopy may be used to determine energy states of samples and track their evolution in time; however, the structural dynamics of matter can only be extracted from that information by indirect methods. We present here direct techniques for studying laser-perturbed substances in the spatiotemporal continuum where matter is probed with ultra-short electron and X-ray pulses. We also describe the first series of the experiments performed using a femtosecond electron diffractometer and picosecond transmission electron microscope at the Institute of Spectroscopy, Russian Academy of Sciences based in Troitsk, Moscow.
