Laser beam divergenceand spot size

Beam divergence refers to the phenomenon where a laser beam expands or spreads out as it travels away from its source. This characteristic is crucial because it affects the focusability and intensity of the beam over distances, impacting applications such as communication, sensing, and laser cutting.

collimated beam: A collimated beam is a laser beam that maintains a constant width over a long distance, exhibiting minimal divergence, which is ideal for many precision applications.

laser mode: Laser mode refers to the spatial distribution of the laser light within the resonator, which influences the divergence and overall characteristics of the emitted beam.

M² factor: The M² factor is a measure of the quality of a laser beam, indicating how close the beam is to an ideal Gaussian beam; lower values represent better beam quality and lower divergence.
