WebMar 31, 2024 · Here, z R is the Rayleigh range of the beam given by. The phase radius of curvature of the beam is a function of the distance from the beam waist, z: This means that the radius is infinite at waist location z = 0, reaches its minimum of 2z R at z = z R, and asymptotically approaches infinity as z approaches infinity. WebRayleigh Range (ZR) is the distance from the beam waist where the beam radius has increased 1.414 times its initial value. This is the point at which the area of cross-section is doubled. If we focus a laser beam, at the focal point, theoretically the intensity goes to …

"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.
