Abstract A seed laser oscillating at different frequencies is proved to have the potential to mitigate the stimulated Brillouin scattering (SBS) effect in a fiber amplifier, which may increase the emission power of a coherent beam combination (CBC) system greatly. In this study, a basic mathematical model describing the multi-wavelength CBC is proposed on the fundamentals of CBC. A useful method for estimating the combination effect and analysing the feasibility and the validity of the multi-wavelength coherent combination is provided. In the numerical analysis, accordant results with four-wavelength four-channel CBC experiments are obtained. Through calculations of some examples with certain spectra, the unanticipated excellent combination effect with a few frequencies involved is explained, and the dependence of the combination effect on the variance of the amplifier chain length and the channel number is clarified.

Online attention
Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
