Rayleigh length calculation
WebThe beat length (L p) is the length over which a 2π phase retardation is introduced between the two components. Beat length is wavelength dependant and is related to birefringence, B, by the following equation: This can lead to visible fringes along the fiber length where light on fast and slow axes interferes, and the beat length is the ... In optics and especially laser science, the Rayleigh length or Rayleigh range, , is the distance along the propagation direction of a beam from the waist to the place where the area of the cross section is doubled. A related parameter is the confocal parameter, b, which is twice the Rayleigh length. The Rayleigh length is particularly important when beams are modeled as Gaussian beams.
