A beat wave approach to harmonic generation in chiral media
Raoul Trines, Holger Schmitz, Robert Bingham +4
We extend the beat-wave framework for laser harmonic generation - where spectra form regular lattices in Fourier space - to the nonlinear response of isotropic chiral media driven…
Dynamical symmetries in laser harmonic generation via a cubic nonlinearity
Raoul Trines, Holger Schmitz, Martin King +2
In our earlier work on harmonic generation with complex light [Nature Communications 15, 6878 (2024)], we demonstrated how the harmonic spectrum of a complex laser beam in a nonlin…
Suppression of pair beam instabilities in a laboratory analogue of blazar pair cascades
Charles D. Arrowsmith, Francesco Miniati, Pablo J. Bilbao +28
The generation of dense electron-positron pair beams in the laboratory can enable direct tests of theoretical models of -ray bursts and active galactic nuclei. We have successf…
A tuneable frequency comb via dual-beam laser-solid harmonic generation
Raoul Trines, Holger Schmitz, Martin King +2
A high-power laser pulse at normal incidence onto a plane solid target will generate odd harmonics of its frequency. However, the spacing of the harmonic lines in this configuratio…
