The Thermal Discouragement Beam (referred by GLaDOS as "deadly laser,") is a Test Chamber mechanic introduced in Portal 2.

The Beam is fired in a straight line from an immovable device built into the wall or ceiling of a Test Chamber. Each Beam is usually coupled with one Receptacle, and multiple Beams with multiple Receptacles may be present within a single Test Chamber. Directing the Beam into the Receptacle will activate certain mechanics that are crucial in reaching the chamber exit. The Beam can also be used in conjunction with Relays, which are small nodes built into the floor of some Test Chambers. Relays are activated when the Thermal Discouragement Beam passes through them, and multiple Relays must often be activated using a single Beam. Once all Relays are activated, specific Test Chamber mechanics will be triggered, similarly to the activation of a Receptacle.

Thermal Discouragement Beams can be angled in certain directions with the use of the Discouragement Redirection Cube and portals. Additionally, the beam holds the ability to travel through transparent objects such as glass. They can also be used as a weapon, as they cause Turrets, with their large ammunition loads, to heat up and explode. Touching the beam while on the ground will push the player away, as well as deal a small amount of damage. Prolonged exposure will result in death.

The beam is a replacement for the High Energy Pellet from Portal as in the first test chamber in which you see it (a copy of Portal Test Chamber 06) an emitter of the pellet is replaced by an emitter for the Beam. The two can both: Destroy turrets,activate elements, and have the direction that they are moving in shifted.
