Abstract

Abstract

The paper studies the influence of frequency components on coherent combining efficiency by using frequency components with different central spectral lines and spectral widths. Experiment results show that closer central spectral lines lead to higher coherent combining efficiency; the coherent combining efficiency is higher when the spectral width is wider and the spectral shapes are similar, which can be close to the ideal value of 100%. The coherent combination of two Er-doped fiber lasers by using frequency components with the same central spectral line and width is achieved, of which the output power is 375 mW, and the coherent combining efficiency is as high as 99.3%.
