Laser beam quality

Laser beam quality refers to how well a laser produces a focused, precise, and consistent beam of light. High-quality laser beams are narrow, uniform, and can be concentrated into a small spot, allowing for efficient cutting, welding, or imaging. It is often measured by a parameter called M², where a lower value indicates a beam closer to an ideal, perfect laser with minimal divergence and diffraction. Good beam quality means the laser’s light remains tight and stable over distance, enhancing its effectiveness and accuracy in various applications.
