They look like props from ALIEN, but these are actually Soviet laser guns–no shit:

Handheld laser weapons developed in the 1980s for cosmonauts. These futuristic pistols used pyrotechnic flashbulb ammunition, and their primary function was to disable optical sensors on enemy spacecraft or satellites. Allegedly the laser beams of these recoilless guns were energetic enough to burn through a helmet visor, or to blind anybody from 65 feet.
