We present an analysis of the transverse supermode competition mechanism in multicore fiber lasers based on rate equations extended to fibers with multiple cores. The model is used to analyze 7-core and 19-core fiber lasers with three commonly used feedback mechanisms as boundary conditions: butt-contact mirror or fiber Bragg grating, Talbot cavity, and collimating lens plus mirror. For the two last-named cases, different feedback (reflection) factors for different modes result from the diffraction effect. The diffraction effect favors the in-phase supermode. Because of mode mixing, a pure in-phase supermode is not obtained. However, for the 7-core fiber laser the in-phase mode can dominate the output.
