Beam m2

Webthe beam waist (in the propagation direction) where the beam radius is increased by a factor of √2 (which is equal to a doubling of the beam area). For beams with a non-perfect beam quality, the Rayleigh Range is decreased by a factor which is called the beam quality factor M² (or, k=1/M² which is also used occasionally). WebApr 12, 2016 · M² is one of the most common metrics used in laser beam diagnostics. Although M² is listed as a beam quality metric, a more correct definition would be a beam propagation factor (Siegmann 1998). The strict definition of M² is. Where ω is the real beam's beam waist, θ is the real beam's divergence angle, ω0 is an ideal beam's beam …
