Abstract
The separation of half-maximum intensity points of a focused truncated coherent Gaussian beam is evaluated. The results differ appreciably from the conventional values used in the past. This result is important in areas where the resolution of two optical beams is required, as, for instance, in determining the optimal separation of elements in a detector array used to identify these beams.
