It is essentially an assisted lightning. UV ionization and electric discharge cooperate to create a directed, conducting channel.

Organics absorbs UV strongly. However, the inventors claims that no permanent blindness will ensue sounds not quite convincing. They say some recent UV semiconductor laser breakthrough in Poland (?) could shrink the device to the size of a flashlight.

The current design study assumes something mounted on a vehicle, a
kind of a crowd control thing. A few cases of "accidently" burned
retina could come handy I can imagine. Of course voltage can also be
boosted to lethal levels...

One could use twin beams. No need for that, if mounted on a vehicle.
