【Abstract】 An assumption that if the sum (2p+l+1) of mode order is equiv alent,then these modes will have same intensity proportion in the mixing modes i s proposed through studying the mode distribution of mixing mode laser.A simula tion for the mixing mode is realized with a computer.The theoretical simulated r esults are identical with the mixing mode distribution measured in experiments.T he intensity proportion of various high-order modes in the mixing mode can be s imulated and estimated with this method.更多还原
