…Beam Parameter Product (BPP).
In some cases, people prefer the Beam Parameter Product (BPP) in order to specify beam quality
(alternatively to the Beam Quality Factor M²). The Beam Parameter Product of a laser beam is defined as
the product of beam radius (measured at the beam waist)…

cut direction changes.
Figure 4 shows that the Coherent HyperRapid NX operating at 355 nm delivers a beam symmetry
of >90% over a depth of focus of more than 500 µm when focused to a beam waist of…

lens focuses the beam to create an internal beam waist, and

Beam Parameter Product
The Beam Parameter Product (BPP) quantifies the
quality of a laser beam and how well it can be
focused. It is the product of a laser beam's far-field
divergence angle (half-angle) and the radius of the
beam at its narrowest point (the beam waist).…
