Thermonuclear bombs are a mixture of fission AND fusion, the amount of energy required to achieve fusion requires fission to provide said energy.
Lasers igniting fusion is a bit of a more of a stretch to create a weapon from (the lasers require 300 mega joules of energy which in turn is 2mj of energy into the reaction and 3mj energy out); it may provide context and more information for fusion as a whole but that information is relevant to both weapons and energy research, not one or the other.
Yes i immediately deleted my answer after i saw i confused the two. My bad, i wasn't aware of NIF before.
(Gonna go ahead and start looking it up some more...)
