摘要
本文讨论了单模和多模激光束的空间相干性,在多模激光器中单程相移非简并的模式间是完全不相干的,但单程相移简并的模式间可以发生相干的.
The spatial coherence of singular mode and multi-modes laser beam has been discussed. As a result, the singUlar mode beam is completely coherent. In the multi-modes laser beam, the nondegenerate modes will be uncoherent, but the degenerate modes can be coherent.
