摘要：

A Young's interferometer has been used for spatial coherence measurements of the 23 mm diameter laser beam provided by a XeCl laser fitted with a super-Gaussian resonator of magnification factor M=7. It has been found that the fringe visibility reduces from 0.8 to 0.1 by increasing the slit distance from 4 mm to 15 mm, the transverse coherence degree of the laser beam being determined by the geometric constraints imposed by the unstable resonator.
