WebMar 31, 2024 · Gaussian beam theory. Consider an ideal Gaussian beam with waist w 0. As shown in the schematic below This Gaussian beam can be described using any two of the three parameters: wavelength λ; beam waist w0; divergence angle θ; The beam size is a function of the distance from the waist. WebThe BPP can also be defined for non-Gaussian beams. In that case, second moments should be used for the definitions of beam radius and divergence. The smallest possible beam parameter product is then achieved with a diffraction-limited Gaussian beam; it is λ / π. For example, the minimum beam parameter product of a 1064-nm beam is ≈ 0.339 ...
