Beam diameter - Wikipedia

In laser science, the parameter M , also known as the beam propagation ratio or beam quality factor is a measure of laser beam quality. It represents the degree of variation of a beam from an ideal Gaussian beam. It is calculated from the ratio of the beam parameter product (BPP) of the beam to that of a Gaussian beam with the same wavelength. It relates the beam divergence of a laser beam to the minimum focussed spot size that can be achieved. For a single mode TEM00 (… WebbThe beam diameter or beam width of an electromagnetic beam is the diameter along any specified line that is perpendicular to the beam axis and intersects it. Since beams typically do not have sharp edges, the diameter can be defined in many different ways. Five definitions of the beam width are in common use: D4σ, 10/90 or 20/80 knife-edge, 1/e 2, … flooding in groton ct

Webband therefore the beam quality factor becomes. M 2 = Θ ⋅ w 0 λ ⋅ π. where radius w 0 is the minimum radius for the real beam. A Gaussian beam has M²=1, while all other beams will have M²>1. Moreover, for a given beam radius, the Gaussian beam has the smallest possible beam divergence. http://www.firstlight-laser.com/phish.html WebbFigure 1: The structure of a laser diode causes the elliptical beam shape typically associated with laser diodes.

In laser science, the beam parameter product (BPP) is the product of a laser beam's divergence angle (half-angle) and the radius of the beam at its narrowest point (the beam waist). The BPP quantifies the quality of a laser beam, and how well it can be focused to a small spot. A Gaussian beam has the lowest possible BPP, , where is the wavelength of the light.
