Can we call this the first laser gun ever? TWI, a British company that does a lot of welding, recently added a pistol grip to its 5 kilowatt industrial cutting tool.

Handheld lasers. Now that's some sci-fi shit there. The machine was originally attached to an automated industrial machine, but can now be gripped by the hands of a person. The tool will fire a beam of light with a wavelength of 1 micron that cuts through steel up to three quarters of an inch thick. You'll need to wear a special suit to wield the gun.
