Rayleigh range laser
Web00 laser beam will have an M2 value of 1. 1 One Rayleigh range is defined as the point on either side of the waist where the beam diameter increases to the square-root of 2 times … WebAug 1, 2024 · Goal is to find beam waist (the focus point) and Rayleigh range, w o and z o using the formula of the radius of beam at a position along z: 2 w ( z) = 2 w o 1 + ( z z o) 2. 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.
