Man builds impressively dangerous laser shotgun

Indeed. Each of the 8 lasers is 5 W, which is similar to the power of an incandescent Christmas light. Hold one of those in your hand and it is hot, but it is spread outover the multiple square cm of the glass bulb. This concentrates that to what, a few square mm, which you can see still takes a couple seconds to do its work. It would definitely cause non-trivial pain on the skin, with at least 2nd degree burns, and I hope he is careful about glancing the beam of shiny metal surfaces.

But all that pales in comparison to a real weaponized laser.
