On the conditional equivalence of phase retrieval algorithms
Jakob Schroeder, Andreas Döpp
Phase retrieval - recovering a complex-valued field from intensity measurements - is typically solved using variants of the Gerchberg-Saxton (GS) algorithm, understood as alternati…
Decoupling acceleration and wiggling in a laser-produced Betatron source
Julien Gautier, Igor Andriyash, Andreas Döpp +11
Betatron radiation is produced in Laser Plasma Accelerators when the electrons are accelerated and simultaneously wiggle across the propagation axis. The mechanisms of electron acc…
CoordGate: Efficiently Computing Spatially-Varying Convolutions in Convolutional Neural Networks
Sunny Howard, Peter Norreys, Andreas Döpp
Optical imaging systems are inherently limited in their resolution due to the point spread function (PSF), which applies a static, yet spatially-varying, convolution to the image.…
Control Systems and Data Management for High-Power Laser Facilities
Scott Feister, Kevin Cassou, Stephen Dann +9
The next generation of high-power lasers enables repetition of experiments at orders of magnitude higher frequency than was possible using the prior generation. Facilities requirin…
All-optical Compton scattering at shallow interaction angles
Andreas Döpp, Igor Andriyash, Kim Ta Phuoc
All-optical Compton sources combine laser wakefield accelerators and intense scattering pulses to generate ultrashort bursts of backscattered radiation. The scattering pulse plays…
Pareto Optimization of a Laser Wakefield Accelerator
F. Irshad, C. Eberle, F. M. Foerster +6
Optimization of accelerator performance parameters is limited by numerous trade-offs and finding the appropriate balance between optimization goals for an unknown system is challen…
