Beam Parameter Product
Product of the Beam Radius in a focus and the far-field beam divergence.
The beam parameter product of a Laser beam is defined as the product of beam radius and the Beam Divergence half-angle. The usual units are mm mrad (millimeters times milliradians). The beam parameter product is often used to specify the Beam Quality of a laser beam: the higher the beam parameter product, the lower the beam quality.
