Trines, R. M. G. M.; Fiuza, F.; Bingham, R.; Fonseca, R. A.; Silva, L. O.; Cairns, R. A.; Norreys, P. A.WOS:000301051200006 (Nº de Acesso Web of Science) ; “Prémio Científico ISCTE-IUL 2012” ; 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 for the first time that it can be used, with equal success, to compress laser pulses from nanosecond to picosecond duration. Simulations show up ...
Electron trapping and acceleration on a downward density ramp: a two-stage appr...
Trines, R. M. G. M.; Bingham, R.; Najmudin, Z.; Mangles, S. P. D.; Silva, L. O.; Fonseca, R. A.; Norreys, P. A.WOS:000277355400025 (Nº de Acesso Web of Science) ; “Prémio Científico ISCTE-IUL 2011” ; In a recent experiment at Lawrence Berkeley National Laboratory (Geddes et al 2008 Phys. Rev. Lett. 100 215004), electron bunches with about 1 MeV mean energy and small absolute energy spread (about 0.3 MeV) were produced by plasma wave breaking on a downward density ramp. It was then speculated that such a bunch might be...
