摘　　要：通过研究混合模激光的模式分布 ,提出模阶数之和 (2 p+l+1 )相同的模在混合模中占相同比例的假设 ,用计算机模拟的方法实现了混合模的模拟 ,理论模拟结果与实验测量的混合模分布很好地吻合 ,由此方法可模拟估算出混合模中各高阶模的强度比例。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.
