WebThe beam parameter product (BPP) is another metric used to evaluate the quality of a laser beam. It is defined as the product of the beam radius at the beam waist and the half-angle beam divergence. It is typically reported in mm mrad, and is related to the M 2 factor by: (5)BPP= M 2λ π BPP = M 2 λ π. Since the BPP is directly proportional ...
