Intense short-wavelength femtosecond light pulses delivered by free-electron laser (FEL) facilities allow to investigate the structure and dynamics of nanometer-sized objects via coherent diffractive imaging (CDI) methods. We studied single helium nanodroplets doped with xenon using extreme ultraviolet (XUV) femtosecond light pulses delivered by the FERMI FEL. When irradiated by a high power infrared (IR) laser pulse, a nanoplasma will be ignited inside the droplets that can be observed in the diffraction pattern from a delayed XUV pulse. The nanoplasma propagation and destruction of the droplets was traced via single-particle imaging from femtoseconds up to hundreds of picoseconds after IR excitation.
