Laser Beam
A laser. Laser beams are intense and concentrated beams of light that have the ability to cut through various materials, including other light sources.
Light beams are photon particles that can be radiated/emitted in a beam, or concentrated in a stream (also known as a LASER - Light amplification by stimulated emission of radiation.)
A strongly concentrated light is called a laser.
