Abstract

Phase maps of optical wave fields are found to consist primarily of phase saddles strung between phase singularities (vortices). Phase extrema (maxima or minima) appear to be absent in the phase fields of laser beams, and are relatively rare in the phase fields of speckle patterns. Theoretical models are presented that help explian this unexpected result. The relationship between stationary points of phase and stationary points of amplitude is also considered.
