Hydrogen may be compressed to more than 10,000 times liquid density by an implosion system energized by a high energy laser. This scheme makes possible efficient thermonuclear burn of small pellets of heavy hydrogen isotopes, and makes feasible fusion power reactors using practical lasers. 

Laser-driven implosion of thermonuclear fuel to 20 to 40 g cm–3

Inertial fusion requires the compression of fusion fuel to densities approaching 1,000 times the density of liquid DT. Compression of DT to densities in the range of 100 to 200 times its liquid

High Density Transition Laser Driven Implosions

In the scheme of inertial confinement fusion, the conditions for fuel ignition have to be economically achieved by applying an isentropic compression. For laser fusion, required final densities range

Thermonuclear fusion by high-power lasers

It may be possible to ignite small deuterium-tritium pellets by the focused radiation of powerful lasers. Crucial for the success of this alternate approach to fusion energy is the understanding of

Laser induced implosion and thermonuclear burn

In high density laser induced fusion, the key idea is laser implosion of hydrogen isotope microspheres to approximately 10,000 times liquid density in order to initiate efficient thermonuclear

Ignition condition for a superdense plasma

The generation of high density DT plasmas by focusing several laser beams on a pellet is discussed in terms of ignition conditions for superdense systems. The superdense plasma is considered to

The dynamics of high compression of laser fusion targets

The dynamics of laser-imploded pellets are studied to isolate those features which are essential to achieving high compression and large ⟨ρR⟩. Under the ideal conditions assumed here (e.g. no photon

Enhancement in thermonuclear reaction rates in a dense plasma

FOR laser-driven fusion, a number density of the order 1026 cm−3 is usually envisaged1,2; here I consider the effects of the presence of a medium on the nuclear reaction rates3 and show the

A model laser-compression experiment

The compression of plasmas by laser beams to produce a significant thermonuclear energy requires very sophisticated experimental techniques and equipment, costing millions of dollars. We review here

Extremely high-pressure generation and compression with laser implosion plasmas

We have tested a scheme for using laser implosion plasmas to generate pressures in the gigabar (100 TPa) regime. Cone-in-shell targets employed in fast ignition of inertial confinement fusion were

Adiabatic wall focusing of intense ion beams for the ignition of thermonuclear microexplosions

It is shown that an intense can beam can be adiabatically and spherically symmetric focused onto a center of convergence by a Prandtl-Meyer flow inside a curved concave wall. The method can be

The Work of Many People.

The story cannot be rightly told without mentioning many of the people whose contributions made the hydrogen bomb possible, but it is even more difficult to attempt any kind of evaluation of the importance of each contribution.
