摘要：

In a general way, study on the distributions of laser modes is under the condition that the modes are regularly distributed. In fact, because of the misalignnent of resonator, sometimes the output laser modes are irregular, and because of the superposition of laser modes, and the disturbance of the atmosphere in the process of propagation, laser beams output are partially coherent. In this paper, with the aid of the computer, the far field distributions of some laser modes and the influence of spatial coherence on the distributions are discussed.
