And how long after will portable versions be available?
The sooner the better. Spare battery packs, power cells or whatever they will be called will undoubtedly weigh less than clips full of bullets.
From the article:
With the major hurdle overcome, the next step would be to take the laser from the laboratory to the field and begin shooting down missiles with it, Strickland said.
The Northrop laser produced a beam at more than 105 kilowatts, which is akin to focusing more than 1,000 100-watt light bulbs on a small spot. The intensity of the light would be comparable to that on the surface of the sun.
Forget about missiles, use that on enemy infantry. They'll run screaming in terror like they were fighting the Martians in
War of the Worlds. That would make it far less likely that anyone would want to cross us. Of course, that only applies to sane people. Terrorists will still push their luck.
