摘　　要：利用自成像效应进行半导体列阵激光器锁相是一种重要的外腔锁相技术,所构成的共振腔可分为Talbot腔和带相位补偿板的Lau腔。我们用Fox-Li方法计算了共振模式。本文给出了Talbot腔的计算结果和分析,表明同相和反相模的损耗随腔长变化存在临界点。Self-imaging effects are an important mechanism for phase-locking of laser arrays. The self-imaging cavities include the one with phase corrector (Lau cavity) and the other one without phase corrector (Talbot cavity). In this paper, the Talbot cavity is analysed in terms of the Fox-Li treatment. It is shown that the diffractive losses of the in-phase mode and the out-of-phase mode have a cross over point with respect to the cavity interval.
