Laser

A laser, which stands for "Light Amplification by Stimulated Emission of Radiation," is a device that emits a narrow beam of light with a specific wavelength. Unlike ordinary light, which spreads out and contains multiple colors, laser light is coherent, meaning the light waves are in sync and travel in the same direction. Lasers are used in various applications, including medical treatments, barcode scanning, cutting materials, and telecommunications. Their precision and intensity make them ideal for tasks requiring accuracy and control. Overall, lasers play a significant role in technology and everyday life.
