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.
