Rayleigh beamwidth

WebThe beam diameter or beam width of an electromagnetic beam is the diameter along any specified line that is perpendicular to the beam axis and intersects it. Since beams … Webwhere w 0 is the beam waist (the smallest radius of the Gaussian beam) and z R is the Rayleigh length: The beam diameter is simply twice the beam radius, and can be measured anywhere along the propagation axis. When you focus a Gaussian beam with a lens of focal length f, the beam waist (or laser spot size equation) becomes:
