Journal ArticleDOI

Stuart Mangles,C. D. Murphy,C. D. Murphy,Zulfikar Najmudin,Alexander Thomas,John Collier,A. E. Dangor,E. J. Divall,Peta Foster,J. G. Gallacher,C. J. Hooker,Dino A. Jaroszynski,A. J. Langley,Warren Mori,Peter Norreys,Frank Tsung,R. Viskup,B. Walton,Karl Krushelnick +18 more
TL;DR: High-resolution energy measurements of the electron beams produced from intense laser–plasma interactions are reported, showing that—under particular plasma conditions—it is possible to generate beams of relativistic electrons with low divergence and a small energy spread.
Journal ArticleDOI

J. Hooker,Karl Krushelnick,Warren Mori,Charlotte Palmer,K. Ta Phuoc,P. P. Rajeev,Jörg Schreiber,M. J. V. Streeter,D Urner,Jorge Vieira,Luis O. Silva,Zulfikar Najmudin +26 more
TL;DR: Three-dimensional particle in cell simulations show that the intensity within the guided filament is amplified beyond its initial focused value to a normalized vector potential of a0>6, thus driving a highly nonlinear plasma wave.
Journal ArticleDOI
Specular reflectivity of plasma mirrors as a function of intensity, pulse duration, and angle of incidence
TL;DR: The specular reflectivity of plasma mirrors formed by sub-picosecond pulses from a titanium:sapphire laser has been measured for different angles of incidence and for two different pulse lengths as a function of the laser intensity as discussed by the authors.
Journal ArticleDOI

TL;DR: In this paper, the detection of a large-amplitude laser-driven wake field is reported for the first time, demonstrating photon acceleration, and several features characteristic of photon acceleration in wake fields, such as splitting of the main spectral peak and asymmetries between the blueshift and redshift for large shifts are observed.

TL;DR: Measurements of proton emission have been made from a variety of solid targets irradiated by a 60-fs, 200-mJ, 7 x 10(18)-W cm(-2) laser system operating at 2 Hz, finding optimum target conditions in terms of target material and thickness.
