The Fresnel diffraction field of a truncated gaussian beam diffracted by a circular aperture is investigated. A new parametrization is introduced which allows the changes of the truncated beam in comparison to the untruncated one to be determined with the aid of three dimensionless parameters: the beam truncation ratio, the defocusing and the normalized radial distance. The limitations of the method are discussed.
