Rayleigh distribution equation

WebThe Rayleigh range of a Gaussian beam is defined as the value of z where the cross-sectional area of the beam is doubled. This occurs when w (z) has increased to √2 w 0. Using Equation 4, the Rayleigh range (z R) can be expressed as: (5)zR = πw2 0 λ z R = π w 0 2 λ. This allows w (z) to also be related to z R: WebJun 21, 2016 · The Rayleigh distribution Equation (1) can be considered . ...
