Portal Denial System Electrolaser Intruder-Zapper

The Portal Denial System is not like those other laser-guard systems you've seen in the movies. The movie systems, which are typically guarding something very valuable, make beautiful laser light shows like you might have seen in a 1980's nightclub.

Ionatron's Portal Denial System, on the other hand, is what an intelligent (and angry) insect would make if insects could design a human-zapper.

The device beams an ultraviolet laser across the doorway; this causes a localized atmospheric bloom - the air ionizes into a plasma. Since this laser-induced plasma channel (LIPC) is electrically conductive, a powerful electric current can be sent across the doorway via the channel.


(Portal Denial System Laser-Induced Plasma Channel Electrolaser)

If you're wondering how much juice can be sent across the doorway, keep in mind that electrolasers can also be used to study lightning, since both use plasma channels as a conduit for electricity.
