Web8 apr. 2024 · In the first approach, you start with the divergence formula in Cartesian then convert each of its element into the cylindrical using proper conversion formulas. The partial derivatives with respect to x, y and z are converted into the ones with respect to ρ, φ and z. WebHalf of the divergence angle can be calculated as . where w 1 and w 2 are the radii of the beam at z 1 and z 2. Like all electromagnetic beams, lasers are subject to divergence, which is measured in milliradians (mrad) or degrees. For many applications, a lower-divergence beam is preferable. Spot size: Spot size is nothing but the radius of the ...
