Description Retrieves the Gaussian beam overlap from a specified coherent optical source.
Syntax overlap = GetSourceBeamOverlap ( n )
Parameters overlap (Double) Returns the amount of overlap in the coherent rays.
n As Long Node number of the source.
Remarks This function retrieves the Gaussian beam overlap from a specified optical source. The overlap represents the fraction overlap in the initial sizes of neighboring Gaussian beams created from a coherent source. Typically the overlap has a value between 1 and 2. The function is of little value for incoherent sources. If there is a problem the function returns 0 and does not set an error.
