Determination of few femtosecond to attosecond electron bunch durations using a passive plasma lens
Andreas Seidel, Carola Zepter, Alexander Sävert +2
Determining the pulse duration of femtosecond electron bunches is challenging and often experimentally invasive. An effective method for measuring the duration based on the time-de…
Ultra-fast yttrium hydride chemistry at high pressures via non-equilibrium states induced by x-ray free electron laser
Emily Siska, G. Alexander Smith, Sergio Villa-Cortes +24
Controlling the formation and stoichiometric content of desired phases of materials has become a central interest for the study of a variety of fields, notably high temperature sup…
Simultaneous Bright- and Dark-Field X-ray Microscopy at X-ray Free Electron Lasers
Leora E. Dresselhaus-Marais, Bernard Kozioziemski, Theodor S. Holstad +40
The structures, strain fields, and defect distributions in solid materials underlie the mechanical and physical properties across numerous applications. Many modern microstructural…
Enhanced ultrafast X-ray diffraction by transient resonances
Stephan Kuschel, Phay J. Ho, Andre Al Haddad +15
Diffraction-before-destruction imaging with single ultrashort X-ray pulses has the potential to visualise non-equilibrium processes, such as chemical reactions, at the nanoscale wi…
Efficient retrieval of phase information from real-valued electromagnetic field data
Alexander Blinne, Stephan Kuschel, Stefan Tietze +1
While analytic calculations may give access to complex-valued electromagnetic field data which allow trivial access to envelope and phase information, the majority of numeric codes…
A Systematic Approach to Numerical Dispersion in Maxwell Solvers
Alexander Blinne, David Schinkel, Stephan Kuschel +3
The finite-difference time-domain (FDTD) method is a well established method for solving the time evolution of Maxwell's equations. Unfortunately the scheme introduces numerical di…
Experimental evidence of radiation reaction in the collision of a high-intensity laser pulse with a laser-wakefield accelerated electron beam
J. M. Cole, K. T. Behm, T. G. Blackburn +21
The dynamics of energetic particles in strong electromagnetic fields can be heavily influenced by the energy loss arising from the emission of radiation during acceleration, known…
Attosecond Control of Relativistic Electron Bunches using Two-Colour Fields
M. Yeung, S. Rykovanov, J. Bierbach +10
Energy coupling during relativistically intense laser-matter interactions is encoded in the attosecond motion of strongly driven electrons at the pre-formed plasma-vacuum boundary.…
Optimisation of the pointing stability of laser-wakefield accelerated electron beams
R. J. Garland, K. Poder, J. Cole +13
Laser-wakefield acceleration is a promising technique for the next generation of ultra-compact, high-energy particle accelerators. However, for a meaningful use of laser-driven par…
Enhanced harmonic generation in relativistic laser plasma interaction
C. Rödel, E. Eckner, J. Bierbach +12
We report the enhancement of individual harmonics generated at a relativistic ultra-steep plasma vacuum interface. Simulations show the harmonic emission to be due to the coupled a…
Relativistic Frequency Synthesis of Light Fields
C. Rödel, E. Eckner, J. Bierbach +12
Waveform shaping and frequency synthesis based on waveform modulation is ubiquitous in electronics, telecommunication technology, and optics. For optical waveforms, the carrier fre…
Thomson backscattering from laser generated, relativistically moving high-density electron layers
Athena E. Paz, Stephan Kuschel, Christian Rödel +4
We show experimentally that XUV radiation is produced when a laser pulse is Thomson backscattered from sheets of relativistic electrons which are formed at the rear-surface of a fo…
A large aperture reflective wave-plate for high-intensity short-pulse laser experiments
Bastian Aurand, Christian Rödel, Huanyu Zhao +8
We report on a reflective wave-plate system utilizing phase-shifting mirrors (PSM) for a continuous variation of elliptical polarization without changing the beam position and dire…
