光纤激光器自成像腔相干组束研究

探讨了3种不同自成像腔，即Talbot腔、自傅里叶变换腔（SF）和傅里叶变换自成像腔实现相干组束的机理和技术难点。介绍了利用光纤激光器，采用傅里叶变换自成像方法，实现1维2路和2维4路激光相干组束的实验情况，功率分别达到122W以及26W。

In this paper, we studied on the principle and technical difficulties of beam coherent combination with three self-imaging cavity, which were Talbot cavity, Self-Fourier cavity and self-imaging cavity of Fourier transform. Finally, we implemented 1×2 fiber lasers coherent combination and 2×2 fiber lasers coherent combination with Self-Fourier cavity, and the coherent output powers reached 122 W and 26 W, respectively.
