Rayleigh distance
WebHow far is it from Raleigh to the South Pole? From Raleigh to the South Pole, it is 8,690.16 mi (13,985.46 km) in the north. Antipode: -35.772095,101.361389. Where do I get to when I … 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.
