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

,
Institute of Spectroscopy, Russian Academy of Sciences, ul. Fizicheskaya 5, Troitsk, Moscow, 108840, Russian Federation

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.
