Demonstration of a 1.1 petawatt laser based on a hybrid optical parametric chirped pulse amplification/mixed Nd:glass amplifier
Erhard Gaul,Mikael Martinez,Joel Blakeney,A. Jochmann,Martin Ringuette,Doug Hammond,Ted Borger,Ramiro Escamilla,Skylar Douglas,W. Henderson,Gilliss Dyer,Alvin C. Erlandson,R.R. Cross,John A. Caird,Christopher A. Ebbers,Todd Ditmire +15 more
TL;DR: The design and performance of the Texas Petawatt Laser, which produces a 186 J 167 fs pulse based on the combination of optical parametric chirped pulse amplification (OPCPA) and mixed Nd:glass amplification, is presented.

Stefano Henin,Yannick Petit,Jérôme Kasparian,Jean-Pierre Wolf,A. Jochmann,Stephan Kraft,Stefan Bock,Ulrich Schramm,R. Sauerbrey,Walter M. Nakaema,Kamil Stelmaszczyk,Philipp Rohwetter,Ludger Wöste,C.-L. Soulez,Sarah Mauger,Luc Bergé,Stefan Skupin,Stefan Skupin +17 more
TL;DR: In this paper, the authors experimentally and numerically characterize multiple filamentation of laser pulses with incident intensities of a few TW/cm2, and observe a new propagation regime where the filament density saturates.
Making spectral shape measurements in inverse Compton scattering a tool for advanced diagnostic applications.
J.M. Krämer,J.M. Krämer,A. Jochmann,M. Budde,Michael Bussmann,Jurjen Couperus,Jurjen Couperus,Thomas E. Cowan,Thomas E. Cowan,Alexander Debus,Alexander Kohler,Alexander Kohler,Michael Kuntzsch,A. Laso Garcia,Ulf Lehnert,Peter Michel,Richard Pausch,Richard Pausch,O. Zarini,O. Zarini,Ulrich Schramm,Ulrich Schramm,Arie Irman +22 more
TL;DR: The potential of inverse Compton scattering as an advanced diagnostic tool is reported by investigating two of the most influential interaction parameters, namely the laser intensity and the electron beam emittance, by investigating the interaction to a nonlinear regime.
Single-shot betatron source size measurement from a laser-wakefield accelerator
Alexander Kohler,Alexander Kohler,Jurjen Couperus,Jurjen Couperus,O. Zarini,O. Zarini,A. Jochmann,Arie Irman,Ulrich Schramm,Ulrich Schramm +9 more
TL;DR: In this article, the spectral characteristics of the emitted Betatron pattern were analyzed using a 2D x-ray imaging spectroscopy technique, together with simultaneously recorded electron spectra and X-ray images, the source size, thus the electron beam radius, was deduced at every shot.

Operation of a picosecond narrow-bandwidth Laser–Thomson-backscattering X-ray source
A. Jochmann,Arie Irman,Ulf Lehnert,Jurjen Couperus,Michael Kuntzsch,S. Trotsenko,Andreas Wagner,Alexander Debus,Hans-Peter Schlenvoigt,U. Helbig,Stefan Bock,Kenneth W. D. Ledingham,Thomas E. Cowan,Roland Sauerbrey,Ulrich Schramm +14 more
TL;DR: The PHOENIX (Photon Electron collider for Narrow bandwidth Intense X-Rays) as discussed by the authors was used at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) to demonstrate the principle of such a light source by colliding picosecond electron bunches from the ELBE linear accelerator with counterpropagating femtosecond laser pulses from the 150 TW Draco Ti:Sapphire laser system.
