Essential criteria for efficient pulse amplification via Raman and Brillouin scattering
R. M. G. M. Trines, E. P. Alves, E. Webb +14
Raman and Brillouin amplification are two schemes for amplifying and compressing short laser pulses in plasma. Analytical models have already been derived for both schemes, but the…
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…
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…
Boosting the performance of Brillouin amplification at sub-quarter-critical densities via reduction of parasitic Raman scattering
R. M. G. M. Trines, E. P. Alves, K. A. Humphrey +6
Raman and Brillouin amplification of laser pulses in plasma have been shown to produce picosecond pulses of petawatt power. In previous studies, filamentation of the probe pulse ha…
A robust plasma-based laser amplifier via stimulated Brillouin scattering
Paulo Alves, Raoul Trines, Kathryn Humphrey +6
It is shown here that Brillouin amplification can be used to produce picosecond pulses of petawatt power. Brillouin amplification is far more resilient to fluctuations in the laser…
Laser-driven shock acceleration of monoenergetic ion beams
F. Fiuza, A. Stockem, E. Boella +7
We show that monoenergetic ion beams can be accelerated by moderate Mach number collisionless, electrostatic shocks propagating in a long scale-length exponentially decaying plasma…
Production of picosecond, kilojoule, petawatt laser pulses via Raman amplification of nanosecond pulses
R. Trines, F. Fiuza, R. Bingham +4
Raman amplification in plasma has been promoted as a means of compressing picosecond optical laser pulses to femtosecond duration to explore the intensity frontier. Here we show fo…
