Rayleigh range is the range where the beam diverges very little and the wavefront is nearly planar: it is where the plane wave approximation is good. Suppose we have a Gaussian beam with 1-cm diameter (that is, beam waist=0.5 cm), what is the beam divergence? What is its Rayleigh range? We need to know the ...
