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. In geometrical optics, vergence describes the curvature of optical wavefronts. Vergence is defined as where n is the medium's refractive index and r is the distance from the point source to the wavefront. Vergence is measured in units of dioptres (D) which are equivalent to m .
