SUMMARY:Matthew Edwards (Princeton): Plasma Sources of Intense Ultrafast 
 Radiation
TZID:Europe/London
UID:20170202-094d43f559892dcb0159936f5acc7dd6@warwick.ac.uk
CREATED:20170112T160745Z
DESCRIPTION:Current high-power lasers can supply coherent pulses with pet
 awatt peak powers and intensities sufficient to drive antimatter jets\, 
 produce bright x-ray radiation\, and accelerate electrons and ions to re
 lativistic velocities. The goal of our research is to develop and apply 
 plasma-based sources of intense ultrafast (sub-picosecond) radiation acr
 oss the electromagnetic spectrum. Here we discuss the creation of intens
 e attosecond pulses using relativistic high harmonic generation from ove
 rdense plasma surfaces and plasma-based laser amplification using stimul
 ated Raman and Brillouin scattering. Relativistic high harmonic generati
 on offers a path to attosecond pulses of unprecedented intensity\, allow
 ing the study of non-linear optics in the attosecond regime. Raman and B
 rillouin amplification of laser pulses in plasma avoid the damage-thresh
 old limits of current solid-state systems\, potentially producing orders
 -of-magnitude improvements in peak power. Recent advances in understandi
 ng and improving the efficiency of these processes will be covered\, wit
 h a particular emphasis on the use of particle-in-cell simulations.
