Laser scanner

From Memory Alpha, the free Star Trek reference.

A laser scanner is a technological device, utilizing laser technology, that, connected to a modified plasma inverter, can produce a plasma shock.

In 2368, Geordi La Forge combined the two devices and, through a small hole created by means of a micro-optic drill, was able to send enough plasma through the hole to temporarily plasma-shock Deanna Troi and Miles O'Brien who were taken over by Ux-Mal criminals. (TNG: "Power Play")
