Lasers work by shooting a really tight beam of light through some fancy mirrors and out the front. Lasers for stage lighting generally have mirrors that allow you to move the beam of the laser around to make shapes in the air and on surfaces that you aim the laser at.

Most laser effects are completely safe to use, especially when the laser effects are not directly in contact with viewers. Except for those effects that come into contact with the audience, there are very few laser effects that are potentially hazardous.
