According to the Department of Defense, directed energy (DE) is “an umbrella term covering technologies that relate to the production of a beam of concentrated electromagnetic energy or atomic or subatomic particles.” The reason science fiction writers and movie producers are interested in directed energy weapons is the same reason our nation is interested.
Directed energy weapons offer speed-of-light delivery – 800 times faster than sound.
The science of the laser to project enough energy to disarm an incoming missile is incredible.
The other science of beam control is even more staggering when you think about it.
When the Star Wars script calls for Luke Skywalker to incinerate the “bad guy,” he pulls out his laser weapon of choice.
