Gaussian beam

A Gaussian beam is a type of light beam that has a specific, smooth intensity profile, resembling a bell curve when plotted. This means it is brightest at the center and gradually becomes dimmer towards the edges. Gaussian beams are commonly used in lasers and optics because they focus well, maintain their shape over a distance, and are easier to manipulate. Their unique properties make them ideal for tasks like cutting, welding, and medical applications, ensuring effective delivery of energy or information while minimizing distortion.
