摘要：

The spatial wave front characteristics of a laser were examined by two beam interference after amplitude division. Complex interference patterns were observed and are interpreted as due to a helical form of the phase front. This unusual form is implicit in previous analyses of cavity eigenfunctions, but the properties of such a helical co-phasal wavefront have not apparently been previously studied. © 1979.
