Nicholas Hopps,Colin N. Danson,Stuart Duffield,David Egan,Stephen Elsmere,Mark Girling,Ewan Harvey,David Hillier,Michael L. Norman,Stefan Parker,Paul Treadwell,David Winter,Thomas H. Bett +12 more
TL;DR: The Orion laser facility at the Atomic Weapons Establishment (AWE) in the UK has recently been completed and key performance data of the facility's laser systems are presented.
Journal ArticleDOI
Binary-phase zone plate arrays for the generation of uniform focal profiles
TL;DR: A focusing system that uses a novel binary-phase optic capable of producing efficient two-dimensional uniform top-hat intensity optical and x-ray profiles is reported on.
Journal ArticleDOI

Norman,Stefan Parker,Stephen Rothman,Michael Rubery,Paul Treadwell,David Winter,Thomas H. Bett +28 more
TL;DR: The Orion laser facility at the atomic weapons establishment (AWE) in the UK has been operational since April 2013, fielding experiments that require both its long and short pulse capability as mentioned in this paper.
Journal ArticleDOI
Binary phase zone-plate arrays for laser-beam spatial-intensity distribution conversion
TL;DR: In this paper, a diffractive element composed of a binary phase zone-plate array is proposed to condition the intensity distribution in the focal plane of a conventional refractive lens to generate a flattop intensity envelope on target.
Journal ArticleDOI
Ultrahigh contrast from a frequency-doubled chirped-pulse-amplification beamline.
David Hillier,Colin Danson,Stuart Duffield,David Egan,Stephen Elsmere,Mark Girling,Ewan Harvey,Nicholas Hopps,Michael J. Norman,Stefan Parker,Paul Treadwell,David Winter,Thomas H. Bett +12 more
TL;DR: Frequency-doubled operation of a high-energy chirped-pulse-amplification beamline is described and type-I second-harmonic generation was achieved using a 3 mm thick 320 mm aperture KDP crystal.
