%X Propagation stability of non-paraxial beam in nonlinear Kerr media is investiga ted by using the linear stability method.Both theoretical anal ysis and numerical simulation show that the modulation instability gain spectrum has thr ee d ifferent distribution features, which are determined by ap 0, where a a nd p 0 represent the non-paraxial parameter and the incident power, respec tively. Furthermore, the corresponding criterion is given to distinguish the thr ee different distributions.
