WebA lens actually implements a Fourier transform. So the relationship between the beam size before the lens and the size of the focus (beam radius at focus: w f) is governed by this Fourier relationship between Gaussian functions: (1) w f = λ f π w 0. Often the beam size is given by the aperture size of the system (lens). WebThe Rayleigh range of a Gaussian beam is defined as the value of z where the cross-sectional area of the beam is doubled.
