Webbest fitting gives you the beam waist. Determine the Rayleigh range. (b) p, as a function of the propagation distance and compare with Eq. (2). (i) (4) to calculate θ with a known wavelength. (ii) Θ by plotting them against the distance and calculating the slope. ) Calculate the value of M2 by using Eq. (5). TSH 2009 In probability theory and statistics, the Rayleigh distribution is a continuous probability distribution for nonnegative-valued random variables. Up to rescaling, it coincides with the chi distribution with two degrees of freedom. The distribution is named after Lord Rayleigh . A Rayleigh distribution is often observed when the overall magnitude of a vect…
