Thermal electron transport plays an important role in the performance of direct-drive inertial-confinement-fusion targets. The laser energy absorbed in the corona is carried into the dense target through thermal electron transport and is converted into kinetic energy through the ablation process. The efficiency of the target drive and of the absorption of the laser light depend to a large exten...

A patent pending device has been created, and successfully used, to fuse tissue membranes as an alternative to sutures or staples. The joining, or coaptation, is accomplished through the controlled application of laser heating to induce protein denaturation and subsequent renaturation across the interface. Lasers have been used by a number of researchers to close wounds in controlled laboratory...

We find the solutions of the Dirac equation for two plane waves (laser beams) and we determine the modified Compton formula for the scattering of two photons on an electron. The practical meaning of the two laser beams is, that two laser beams impinging on a target which is constituted from material in the form a foam, can replace 100-200 laser beams impinging on a normal target and it means th...

Abstract Recent experiments with high-intensity lasers have shown record production of α -particles by irradiating boron-hydrogen targets. This opened the way to completely new studies on proton-boron fusion multiple goals: i) related nuclear fusion. The reaction produces 3 and releases a large energy. It is considered an interesting alternative deuterium-tritium because it no neutrons, therefo...

156 LLE Review, Volume 92 Introduction In inertial confinement fusion1 experiments, shells filled with deuterium (D2) or a deuterium–tritium (DT) mixture are heated by either direct laser illumination or soft x-ray radiation in a laser-heated hohlraum. The target is compressed to conditions under which thermonuclear fusion occurs. The most-promising target designs consist of a layered cryogenic...

LLE Review, Volume 79 121 The National Ignition Facility (NIF) is currently under construction at Lawrence Livermore National Laboratory (LLNL). One of the primary missions of the NIF is to achieve fusion ignition by means of inertial confinement fusion (ICF). Two main approaches have been considered for achieving thermonuclear yield in ICF. The first approach, known as indirectdrive ICF,1 encl...

54 LLE Review, Volume 86 Introduction High-gain inertial confinement fusion (ICF) requires uniform compression of a spherical capsule to a state of high density and temperature;1–3 current research is aimed at finding ways to achieve this goal. This article describes how a range of traditional and new nuclear diagnostics are used to study the compression performance of deuterium-tritium (DT)-fi...

The dissimilar joint between aluminum/titanium alloys (Al 6082 and Ti G2) were successfully achieved by CO2 laser welding with a single pass and without filler material using the overlap joint design. Laser welding parameters ranges combinations were experimentally determined using Taguchi approach with the objective of producing welded joint with acceptable welding profile and high quality of ...

The ablator couples energy between the driver and fusion fuel in inertial confinement fusion (ICF). Because of its low opacity, high solid density, and material properties, beryllium has long been considered an ideal ablator for ICF ignition experiments at the National Ignition Facility. We report here the first indirect drive Be implosions driven with shaped laser pulses and diagnosed with fus...
