Abstract

The study of dynamics of phase transitions and the breaking of chemical bonds in a reaction is an important and rapidly growing area of modern science. The interest to this topic is gained both by its fundamental aspect and possible applications in fast switching. Some structural changes may occur on a timescale of tens of femtoseconds and the detection of their dynamics requires an advanced measuring technique. The most widely used method for study of the structural dynamics is an all-optic technique, on which the material is excited by a light pulse. The induced structural changes are accompanied by a change in the optical properties of the material that can be measured by second optical probe pulse. Unfortunately, the optical properties of a studied material are not always directly linked to the atomic order and can be influenced by other factors. The direct access to the atomic motion can be obtained by time-resolved x-ray and electron diffraction.
