Abstract
The appearance of wave front dislocations under interference among bea ms of simple wave fronts is considered. It is shown that even two beam s with smooth wave fronts can cause the formation of screw dislocation s. The screw dislocations are formed at the point where the lines of e qual intensity of two beams cross the minima of an interference patter n.
