A Thermal Discouragement Beam

The Aperture Science Thermal Discouragement Beam, also known as simply Discouragement Beam, or even simply deadly laser by GLaDOS, is essentially a very hot laser, hot enough to burn skin. It is a beam fired from an immovable device that is used to activate Discouragement Relays and Discouragement Receivers. It can be redirected with Discouragement Redirection Cubes, and Reflection Gel. The generator can be placed on the wall, floor, or ceiling. The laser generated by the Thermal Discouragement Beam Generator can destroy Turrets, as well as kill players. The beam is also capable of going through Glass elements and such. In Portal 3, there is a testing element which a beam can go through on one side, but reflects off the other.
