摘要：

It is shown that for paraxially propagating beams of any state of coherence, the width changes along the propagation axis with the same law as that of a gaussian beam. A quality factor related to the rate of width change can then be defined. A formula expressing this quality factor in terms of the cross spectral density across the beam is derived.
