laser-activated fusion — nuclear fusion Interior of the U.S. Department of Energy's National Ignition Facility (NIF), located at Lawrence Livermore National Laboratory, Livermore, California. The NIF target chamber uses a high-energy laser to heat fusion fuel to temperatures sufficient for thermonuclear ignition. The facility is used for basic science, fusion energy research, and nuclear weapons testing.

The deuterium-tritium (D-T) fusion reaction is an exoergic process that releases a positive Q-value of $2.8 \times 10^{- 12}$ joules per reaction.1

In terms of the energy carried by the reaction products, the D-T process produces an alpha particle with an energy of 3.5 million electron volts (MeV) and a neutron with an energy of 14.1 MeV.2
