Popis:	The Sommerfeld diffraction theory is extended to the case of extremely short pulses. It is shown that in the far field the energy density distribution of the diffractional pattern is transformed into Gaussian one, when the plane wave with the uniform radial amplitude distribution and one period of oscillations falls upon the circular aperture. In the case of the focusing of the Gaussian beam with one period of oscillations the energy density distribution in the focal plane differs from the Gaussian one.© (1999) COPYRIGHT SPIE--The International Society for Optical Engineering.
