High orbital angular momentum harmonic generation
J. Vieira, R. M. G. M. Trines, E. P. Alves +5
We identify and explore a high orbital angular momentum (OAM) harmonics generation and amplification mechanism that manipulates the OAM independently of any other laser property, b…
Multidimensional Plasma Wake Excitation in the Non-linear Blowout Regime
J. Vieira, R. A. Fonseca, L. O. Silva
Plasma accelerators can sustain very high acceleration gradients. They are promising candidates for future generations of particle accelerators for several scientific, medical and…
Physical mechanism of the transverse instability in radiation pressure ion acceleration
Y. Wan, C. -H. Pai, C. J. Zhang +8
The transverse stability of the target is crucial for obtaining high quality ion beams using the laser radiation pressure acceleration (RPA) mechanism. In this letter, a theoretica…
Amplification and generation of ultra-intense twisted laser pulses via stimulated Raman scattering
J. Vieira, R. M. G. M. Trines, E. P. Alves +5
Twisted Laguerre-Gaussian lasers, with orbital angular momentum and characterised by doughnut shaped intensity profiles, provide a transformative set of tools and research directio…
