Highly charged ions are formed in the center of composite clusters by strong free-electron laser pulses and they emit fluorescence on a femtosecond time scale before competing recombination leads to neutralization of the nanoplasma core. In contrast to mass spectrometry that detects remnants of the interaction, fluorescence in the extreme ultraviolet spectral range provides fingerprints of...

The combination of intense femtosecond X-ray and NIR pulses produced by Free Electron Lasers (FEL) and synchronized optical lasers, respectively, offers various opportunities to gain detailed insight into atomic photoionization dynamics. After an early study on the linear dichroism in the two-color photoionization of helium at FLASH [1], we have now taken advantage of the availability of...

The ionization dynamics of atomic clusters in intense ultrashort laser pulses has been an active area of research in recent years at near-infrared (NIR), vacuum-ultraviolet, and soft x-ray wavelengths. The dynamics of multi-component nanoplasmas turns out to be interesting model systems for realizing single-shot ultrafast diffraction imaging of large biomolecules in the x-ray domain. Helium...
