I think (correct me if I'm wrong, as this is only a guess) by using knife-edge method I can get beam radiuses at some distances from the beam waist. WebThe Rayleigh length (or Rayleigh range) of a laser beam is the distance from the beam waist (in the propagation direction) where the beam radius is increased by a factor of the square root of 2. For a circular beam, this …

WebFor Gaussian beams, the Rayleigh length is determined by the waist radius w 0 and the wavelength λ: " where the wavelength λ is the vacuum wavelength divided by the refractive index n of the material. For beams with imperfect beam quality and a given waist radius, the Rayleigh length is effectively decreased by the so-called M2 factor.

In optics and especially laser science, the Rayleigh length or Rayleigh range, $${\displaystyle z_{\mathrm {R} }}$$, is the distance along the propagation direction of a beam from the waist to the place where the area of the cross section is doubled.
