X-ray lasers offer new capabilities in understanding the structure of biological systems, complex materials and matter under extreme conditions 1, 2, 3, 4. Very short and extremely bright, coherent X-ray pulses can be used to outrun key... more
Extremely intense and ultrafast X-ray pulses from free-electron lasers offer unique opportunities to study fundamental aspects of complex transient phenomena in materials. Ultrafast time-resolved methods usually require highly... more
We reconstructed the 3D Fourier intensity distribution of monodisperse prolate nanoparticles using single-shot 2D coherent diffraction patterns collected at DESY's FLASH facility when a bright, coherent, ultrafast x-ray pulse... more

Saturable absorption is a phenomenon readily seen in the optical and infrared wavelengths. It has never been observed in core-electron transitions owing to the short lifetime of the excited states involved and the high intensities of the... more
Substrate smoothing for high-temperature condenser operation in EUVL source environments. [Proceedings of SPIE 5751, 140 (2005)]. Regina Soufli, Sherry L. Baker, Susan Ratti, Jeff C. Robinson, Sasa Bajt, Jennifer B. Alameda ...
Extreme ultraviolet (EUV) photoresists are known to outgas during exposure to EUV radiation in the vacuum environment. This is of particular concern since some of the outgassed species may contaminate the nearby EUV optics and cause a... more
The Stardust Interstellar Preliminary Examination (ISPE) is a three-year effort to characterize the Stardust interstellar dust collection and collector using non-destructive techniques. We summarize the status of the ISPE.

The structural dynamics of short-pulse laser irradiated surfaces and nano-structures has been studied with nm spatial and ultrafast temporal resolution by means of single-shot coherent XUV-scattering techniques. The experiments allowed us... more
