Reflection of attosecond x-ray free electron laser pulses.
In order to utilize hard x-ray free electron lasers (XFEL's) when they are extended to attosecond pulse lengths, it is necessary to choose optical elements with minimal response time. Specular grazing-incidence optics made of low-Z materials are popular candidates for reflectors since they are likely to withstand x-ray damage and provide sufficiently large reflectivities. Using linear-optics re...
متن کاملPhotoelectron diffraction from laser-aligned molecules with X-ray free-electron laser pulses
We report on the measurement of deep inner-shell 2p X-ray photoelectron diffraction (XPD) patterns from laser-aligned I2 molecules using X-ray free-electron laser (XFEL) pulses. The XPD patterns of the I2 molecules, aligned parallel to the polarization vector of the XFEL, were well matched with our theoretical calculations. Further, we propose a criterion for applying our molecular-structure-de...
متن کاملFeasibility of a Laboratory X-Ray Laser Pumped by Ultrashort UV Laser Pulses
In order to allow widespread application of soft X-ray lasers there is a strong effort worldwide to use as small as possible pump lasers for plasma production. Short pulse lasers (-c~ 1 ps), particularly in the UV, have attracted much interest, since extremely high intensities (up to 10 ~8 W/cm 2) can be achieved with a relatively high repetition rate. In this article we discuss their merit for...
متن کاملCompression of X-ray Free Electron Laser Pulses to Attosecond Duration
State of the art X-ray Free Electron Laser facilities currently provide the brightest X-ray pulses available, typically with mJ energy and several hundred femtosecond duration. Here we present one- and two-dimensional Particle-in-Cell simulations, utilising the process of stimulated Raman amplification, showing that these pulses are compressed to a temporally coherent, sub-femtosecond pulse at ...
متن کاملExplosions of xenon clusters in ultraintense femtosecond x-ray pulses from the LCLS free electron laser.
Explosions of large Xe clusters ( ~ 11,000) irradiated by femtosecond pulses of 850 eV x-ray photons focused to an intensity of up to 10(17) W/cm(2) from the Linac Coherent Light Source were investigated experimentally. Measurements of ion charge-state distributions and energy spectra exhibit strong evidence for the formation of a Xe nanoplasma in the intense x-ray pulse. This x-ray produced...
