Laser Beam Divergence Calculator — Frequently Asked Questions
Q1 Why do wider laser beams diverge less? ▾
Diffraction is inversely proportional to aperture size; expanding a beam through a collimator dramatically narrows its far-field angular divergence.
Q2 What is the Rayleigh range (zR)? ▾
The distance over which the beam cross-sectional area doubles: zR = π * w0² / λ.
