摘要
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122 W以及26 W。
In this paper, we studied on the principle and technical difficulties of beam coherent combination with three selfimaging cavity, which were Talbot cavity, self-Fourier cavity and self-imaging cavity of Fourier transform. Finally, we implemnted1× 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.
