Influence of optical nonlinearity on combining efficiency in ultrashort pulse fiber laser coherent combining system
文献摘要：
The influence of optical nonlinearity on combining efficiency in ultrashort pulse fiber laser coherent combining sys-tem is investigated theoretically and experimentally.In the theoretical work,a new theoretical algorithm is presented for the coherent combining efficiency,which can be used to quantify the spectral coherence decay induced by optical nonlin-earity imbalance between the sub-beams.The spectral information of the sub-beam is obtained by numerically solving the nonlinear Schr?dinger equation(NLSE)in this algorithm to ensure an accurate prediction.In the experimental work,the coherent combining of two all-fiber picosecond lasers is achieved,and the influence of imbalanced optical nonlinearity on the combining efficiency is studied,which agrees with the theoretical prediction.This paper reveals the physical mecha-nism for the influence of optical nonlinearity on the combining efficiency,which is valuable for the coherent combining of ultrashort pulse fiber laser beams.
