摘要：

We investigate the effects of a finite spectral width on the propagation characteristics of partially coherent gaussian beams. Our results predict that quasi-monochromatic and broad band beams exhibit intensity profiles that are appreciably different from those of monochromatic beams. As the beam propagates in free space, the width and the shape of the intensity profile depend not only on the width and the shape of the spectral profile of the light in the source plane, but also on its coherence properties. We illustrate the general phenomenon of spectrum-enhanced spreading of partially coherent beams for several spectral lineshapes. © 1990.
