We present measurements of the transverse and longitudinal coherence lengths of the fourth harmonic of a 1053-nm, 2.5-ps laser generated during high-intensity (up to ${10}^{19}$ W ${\mathrm{cm}}^{\mathrm{\ensuremath{-}}2}$) interactions with a solid

The interaction of a 1053 nm picosecond laser pulse with a solid target has been studied for focused intensities of up to 1019 W cm-2. The maximum ion energy cutoff Emax (which is related to the hot electron temperature) is in the range 1.0-12.0 MeV

Samples of human rib were collected at autopsy and 20 were selected for marrow fat cell measurement, representing an age range of 16-96 years. The mean diameter of fat cells in red bone marrow of human rib was found to increase from around 48 microns

A technique is demonstrated for optimally generating three-dimensional reconstructions of images formed using a minimal quantity of data. The results are illustrated using thermonuclear α-particles from laser-driven implosions. The images are genera

We have carried out a systematic investigation of implosions of high aspect ratio DT filled shells at the Central Laser Facility, Rutherford Appleton Laboratory. This study has developed directly driven implosions as sources of thermonuclear particle

A novel α-particle backlighting technique has been developed to diagnose laser plasmas, enabling small changes in the thickness modulation to be measured, down to ~0.1 μm. In this technique, a laser-driven implosion of a D–T target produces a bri

Maximum entropy techniques have been developed to image thermonuclear particle emission from laser driven implosions of DT filled microballoons. Spatial resolutions of 5–10 μm have been achieved using two separate techniques: maximum entropy decon

The fast ignitor scheme for inertial confinement fusion requires forward driving of the critical density surface by light pressure (hole boring) to allow energy deposition close to the dense fuel. The recession velocity of the critical density surfac
