Mi van, Beam Divergence?
A bam divergence refers to te angle at which a laser beam expands overdistante. It it is usually measuredy in milliradians (mrad) and indicates how much the beam widens as away from the source.
Calculating Beam Divergence
Ez a divergence angle can be calculated using the beam 's waist size and wonlength. The mott common formulák:

In realworld applications, divergence affects the fókusz and intenzitás distribution of the laser beam. Lower divergence value indicate a more collimated beam, superable for long-distance transmission on.
A Meeturing divergence involves using beam profiling equipment to analize the beam 's size at different distances. Tiss data helps optimize laser system performance for specific tasks.
