Mathematical model of emission from a multichannel laser

A mathematical model is proposed of emission from a multichannel laser regarded as a system of N identical sources with field distributions differing in respect of the phase. A study of far-field distributions of the intensity and of the radiation energy is used to formulate certain general conclusions. The example of a pair of ideal radiators which are not phase locked and have elliptic or rectangular apertures is used to analyze the characteristics of the angular divergence of the radiation.
