laser beams

Coherent light rays

Laser beams are concentrated streams of coherent light, produced by devices that amplify light through stimulated emission.

The beam stays narrow over distance, making lasers useful for cutting, measuring, pointing, and communication.

In science fiction and popular culture, laser beams appear as visible rays of destructive energy: The spaceship's laser beams sliced through the enemy hull.

Real laser beams are often invisible to the naked eye.
