We study the intensity correlation properties of optical vortices passing through a rotating ground-glass (RGG) plate and compare them with those of the TEM(00) mode of an He-Ne laser beam passed through the same RGG. We have observed that the intensity correlation curves for optical vortices decrease much faster than the corresponding curve for a TEM(00) mode of the He-Ne laser. The rate of decay of the correlation increases with the increase of order of the vortices. Our experimentally observed results are supported by exact analytical results.
我们研究了通过旋转毛玻璃（RGG）板的光涡旋的强度相关特性，并将其与通过相同 RGG 的氦氖激光束的 TEM（00）模式的强度相关特性进行了比较。我们已经观察到，光涡旋的强度相关曲线比氦氖激光的 TEM（00）模式的相应曲线下降得快得多。相关曲线的衰减速率随着涡旋阶数的增加而增加。我们的实验观测结果得到了精确解析结果的支持。
