This project extends the previous successful experiments that probe the dynamics of dopant-induced helium (He) nanoplasmas into two directions. On the one hand, He nanoplasmas will be explored in new regimes of light-matter interaction and with new diagnostic methods. He nanoplasma dynamics induced by intense mid-infrared as well as extreme ultraviolet pulses will be probed using correlated single-shot electron imaging spectroscopy and ion mass spectrometry. On the other hand, we will take the control of He nanoplasmas to an extreme by size-selecting the He droplets and by intensity filtering the laser pulses. The application of phase-controlled and polarization-shaped bichromatic laser fields will elucidate the potential and the limitations of controlling electron and ion emission from tailored nanoplasmonic systems. These studies are instrumental for devising novel strategies for laser-based particle acceleration and for assessing radiation damage occurring in free-electron laser-based diffraction imaging.
