Judoon blaster

Judoon blasters were the weapons carried by the Judoon.

Function
The guns shot out a red energy beam, which disintegrated an organic target in one shot. They were able to shoot through glass without difficulty, and make holes in walls. Like most of Judoon technology, the blasters were red in colour. The blasters took a few seconds to charge as seen when a trio of Judoon blasted the Doctor and Martha Jones after the Doctor was identified as a non-Human. It was difficult, but not impossible, to avoid the energy discharge. (TV: Smith and Jones) The weapons had seemingly been advanced slightly by 2009 as when Captain Tybo crashed on Earth his blaster had a much more rapid rate of fire and required little time to charge.
