Individual particle imaging in an ablation plume of a thin metal film

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

We image individual particles flying from a thin metal target following nanosecond laser ablation from the transparent substrate side. Time-resolved imaging of the plume is performed using intensified CCD camera registering either spectrally-integrated thermal emission or Mie scattering signal from a synchronized illumination laser. Individual particles appear as streaks on the image, from which particle velocity distribution is derived. All particles are confirmed to leave the target at the same time. Simultaneous single-shot Mie/Thermal imaging allows to correlate plume structure with particle content.
