Laser beams are focused streams of light produced by a device called a laser. The term "laser" stands for "Light Amplification by Stimulated Emission of Radiation." Unlike regular light, which spreads out in all directions, laser light is coherent, meaning its waves are in sync and travel in the same direction. This property allows laser beams to be very precise and powerful. Lasers have various applications in everyday life and technology. They are used in medical procedures, such as eye surgery, as well as in communication technologies, like fiber optics. Additionally, lasers play a crucial role in manufacturing processes, cutting materials with high accuracy.
