Simultaneous observation of laser-induced tin droplet two-dimensional deformation

By utilizing the combination of multiple dichroic mirrors, droplet detection, synchronization of laser with droplets, and droplet deformation observation in two directions can be realized in a very compact design. A shadowgraph technology is used to investigate the laser-induced tin droplet two-dimensional deformation. Particularly, compressed and propelled targets in side-view and expensed disk-like targets in front-view shad-owgraphs are observed at the same time. In addition, the propulsion and expansion processes of the droplet are presented, keeping consistent with the prediction of the theoretical model. All these results highlight the ability of our compact design for droplet dynamic evolution monitoring.
