Scientists at the Naval Research Laboratory,
Lawrence Livermore National Laboratory, and
other institutions are carrying out a multidisciplinary
program to develop high energy
pulsed lasers and complementary technologies
for fusion energy and defense applications.
For fusion energy, an array of high-energy laser
beams would symmetrically and directly
illuminate a cryogenic target that has been
injected into a chamber. The deuterium-tritium
fuel in the target undergoes thermonuclear burn
and the energy is used to generate electricity.
The attractiveness of this approach lies in its
inherent simplicity, its separable architecture,
and the modular nature of the laser driver. This
lowers development costs and allows multiple
options for the lasers, targets, and chambers.
