摘要：
Based on the off-axis theory, a model for describing the far field with the bipeak structure of a high-power laser diode is proposed. The computed results agree well with the measured far-field data of practical devices. A minimum overall error criterion for fitting the theoretical model with the measured data is also given. The results show that the overall error of this model is less than 5% for popular laser diodes. This model has a simple mathematical structure and can be easily used to design the beam-shaping system and to analyze the propagation properties when the laser beam passes through an optic system.
