ANL/APS/LS-320 Electron beam-based sources of ultrashort x-ray pulses

A review of various methods for generation of ultrashort x-ray pulses using relativistic electron beam from conventional accelerators is presented. Both spontaneous and coherent emission of electrons is considered. Introduction The importance of the time-resolved studies of matter at picosecond (ps), femtosecond (fs), and atttosecond (as) time scales using x-rays has been widely recognized incl...

Efficient cross polarized wave generation for compact, energy-scalable, ultrashort laser sources.

The generation of high contrast and ultrashort laser pulses via a compact and energy-scalable cross polarized wave filter is presented. The setup incorporates a waveguide spatial filter into a single crystal XPW configuration, enabling high energy and high intensity transmission, efficient contrast enhancement and pulse shortening at the multi-mJ level. Excellent XPW conversion of up to 33% (gl...

Ultrashort Pulses

Ultrashort pulses usually are defined as those lasting less than a nanosecond. Low-energetic ultrashort pulses can be used, for instance, as a probe for studying the dynamics of ultrafast processes. Amplifying these pulses can deliver extremely high peak power, allowing applications such as laser particle acceleration, or γ-ray generation via Compton scattering on relativistic electrons. Existi...
