M squared: Measurement, Science & Products

In laser science, the parameter M2, 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…
