Focused gaussian beam spot size
WebSimulation results are presented at various ranges up to 10 km for (1) the beam wander centroid displacement, (2) the kurtosis excess of the irradiance profile, (3) the irradiance profile, (4) the mean-square hot spot displacement from the boresight and from the centroid, and (5) the scintillation index at the optical axis of the beam. WebFor a highly focused beam, there is also a thin lens source that will inject a fully vectorial beam. The cross-section of this beam will be a Gaussian if the lens is not filled, and will be a since function if the lens is filled. ... Gaussian spot size: The beam spot size can be set independently of the source span. The source span should be ...
