Thermal Discouragement Beams in Portal 2.

The Laser Emitter is a testing element in Portal 2. It emits a Thermal Discouragement Beam (hereafter referred to as a 'laser') into a room at a 90 degree angle to the wall on which it is placed. The laser can be used to activate Laser Relays and Laser Catchers. The laser can be redirected using the Reflection Cube or through portals. The laser is harmful to the player, though touching it is not immediately fatal. The laser can pass through both Glass and Grating.

Placement

The Laser Emitter is placed by dragging the icon from the left hand panel into the desired position in the editor. It cannot be placed on a wall adjacent to the entrance or exit or an Observation Room. The Laser Emitter's position within a tile can be tweaked by dragging the diamond-shaped gadget the appears when it is selected.
