高功率光纤激光空间拼接的研究进展

Research progress of high power fiber laser beam space splicing

鉴于当前光纤激光空间拼接的研究成果,归纳出3种不同的拼接类型:利用转向镜的拼接、利用合束器的拼接和利用凹面光栅的拼接。对于每一种拼接方案,本文详细介绍了其实现的原理以及所采用的技术手段,并呈现了这些拼接方案所取得的阶段性成果。

In view of the current research results of fiber laser beam space splicing,three different splicing schemes were summarized,which included the types with steering mirror,fiber combiner and concave grating,respectively.For each splicing scheme,the splicing principle,as well as the adopted technical method are introduced.Further,the achieved phase results by means of these schemes are shown as well.
