The Laser Relay in the Puzzle Maker.
The Laser test elements in-game.

A laser relay is a test element in the map editor. This test element is very similar to a Laser Catcher, but instead, is not attached to a wall or ceiling. The relay is placed on the floor, and a laser can pass through it. This could be useful for using the laser to enable multiple objects at once.
