摘要：

Output spectral and spatial parameters of the two-channel fiber laser operating in an intracavity spectral beam combining mode were investigated. We showed the possibility of the occurrence of a collective lasing mode when various channels participate in the creation of common radiation. We measured spectral and spatial parameters of collective lasing. Conditions of its occurrence and possibility of negative influence on the result of intracavity spectral beam combining were studied both theoretically and experimentally.
