Beugungsstruktur im Nahfeld eines TEM00-Mode-Lasers
Abstract
Experiments concerned with the determination of the beam profile of a pulsed TEM/00/-mode Nd-YAG laser are discussed, taking into account long-range and short-range field characteristics. An investigation is conducted regarding the diffraction of a spherical wave at an iris diaphragm, giving attention to a comparison of the characteristics of the Nd-YAG laser with calculations reported by Campillo et al. (1973). The characteristics of a beam which had been diffracted and focussed are studied with the aid of a He-Ne laser.
