The principle and structure of DCN laserwere introduced in this paper.The EH11 mode approximation in the near field and the far field by Gaussian distributions and the beam property of DCN laserwere studied in detail. The theoretical work well fitted the experimental data.This work is important and necessary for further optical design for EAST tokmak FIR laser interferometer.
