<p>Investigation of laser-matter interaction has been an
important research topic which is closely related to applications in various
fields including industry, military, electronics, photonics, etc. With the
advent of ultrafast transmission electron microscope (UTEM), in situ
investigation of the interaction between pulsed laser and nanostructured
materials becomes accessible, with unprecedented spatial and temporal
resolution. Here, we studied two categories of materials with the help of UTEM,
namely, energetic materials and plasmonic nanostructures. The results
demonstrate that UTEM provides a novel and convenient way for the investigation
the structural and morphological change of energetic materials under external
stimuli at nanoscale. Also, UTEM makes it possible to visualize the
light-induced welding between plasmonic nanostructures at real time, which
helps to reveal more details about the mechanisms involved. Furthermore, we
studied the formation of some novel structures by combing different gold and
silver nanostructure.</p>
