摘　　要：基于非傍轴衍射理论和二极管激光远场光强的实验结果,借助于振幅-位相恢复算法,提出了模拟二极管激光源场分布的一种新方法.给出了模拟步骤,并以双异质结二极管激光为例加以说明.当实验结果准确时,这是一种足够精确的方法,有实际应用意义.Based on the non-paraxial diffraction theory and experimental results of the far-field distributions of diode lasers and by means of the amplitude-phase retrieval algorithm,a novel method for simulating source-field distribution of the diode laser is proposed. The simulation procedure is described and illustrated by the example of a double-heterostructure diode. It is shown that this method is precise enough so long as acurate experimental data are available,and would find some practical applications.
