Laser beam

A laser beam is a focused, coherent stream of light produced by a device called a laser. Unlike regular light, which spreads out in many directions and is made up of different colors and phases, laser light is concentrated into a narrow, intense beam with all the light waves synchronized in wavelength and oscillation. This coherence and directionality allow laser beams to be precise, powerful, and capable of traveling long distances without dispersing. Lasers are used in various applications like medical procedures, barcode scanners, communication, and manufacturing due to their accuracy and controllability.
