Good, but next time post your source as well.Thats not how it works. Every laser has to be focused as, at least with our technology and understanding, it is impossible to project completely parallel beams of light. And compared to the infinite range of ballistics, the distance in which lasers can still be focused is rather low.
Anyway, for practical reasons and aims, laser light are parallel beams. Now if we are talking about huge distances, that might change, but then we should reconsider the targeting systems of the supposed ships and everything else. The reason I insist on this "parallel beams" is to make sure everyone understands that you could, but you don't have to, focus them as if they were flashlights in order to get an acceptable result.
