The characteristics of front end light, a key problem in EFISI(Echelon Free Induced Spatial Incoherence), is analyzed in this paper, and a new partial coherencelight source is researched here.
对无阶梯诱导空间非相干技术中前级光源太弱的问题进行了分析，开展了前级部分相干源的研究工作。

A parallel effort was made by theorists to understand the properties of laser light, to describe its coherence, its classical aspects, and its inherently quantum features.
同时理论物理学家们正努力研究激光的性能，以便阐述其量子性，从而在使激光在实验中作更好的应用。
