Web7 rows · The term FWHM refers to the width of an optical signal at half its maximum intensity. This measure gives the bandwidth of a light source operating at 50% capacity. It is also an important property for … The angle between the maximum peak of radiated power and the first null (no power radiated in this direction) is called the Rayleigh beamwidth. The simplest way to define the width of a beam is to choose two diametrically opposite points at which the irradiance is a specified fraction of the beam's peak irradiance, and take the distance between them as a measure of the beam's width. An obvious choice for this fraction is ½ (−3 dB), …
