Rayleigh range laser
In optics and especially laser science, the Rayleigh length or Rayleigh range, $${\displaystyle z_{\mathrm {R} }}$$, 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 … See more The total angular spread of a Gaussian beam in radians is related to the Rayleigh length by $${\displaystyle \Theta _{\mathrm {div} }\simeq 2{\frac {w_{0}}{z_{R}}}.}$$ The See more • Beam divergence • Beam parameter product • Gaussian function • Electromagnetic wave equation See more WebNote: Results greater than 1,000,000 are rounded to infinity.
