WebThe M 2 factor of a laser beam limits the degree to which the beam can be focused for a given beam divergence angle, which is often limited by the numerical aperture of the focusing lens. Together with the optical power, … WebJul 1, 2024 · In Equation 1, w 0 is the beam waist, θ is the divergence angle of the laser, and λ is the lasing wavelength (see Fig. 1). The divergence angle of a Gaussian beam is determined by Equation 2: 2. The resulting divergence angle can be inserted into Equation 2 to simplify the calculation of the M 2 factor of a Gaussian beam: 3. self build electric cars https://accweb.net
