Rayleigh range推導
WebJun 24, 2016 · The Gaussian Beam Calculator calculates the beam half-width, Rayleigh range, and full-angular width of a Gaussian Beam (TEM 00 ). z R – Rayleigh range 1, the distance along the axis of propagation from the beam wait such that w(z) = √2w w ( z) = 2 w. Since the beam half-width is a radial distance, the Rayleigh range marks where the cross ...
