中文摘要:
      对色散介质中平面波的积累二次谐波发生问题进行了研究,给出了形式简捷的积累二次谐波振幅和相位的解析表达式,还给出积累二次谐波发生的临界距离。据本文的分析方法,能很好地理解色散介质中积累二次谐波发生的物理过程。
英文摘要:
      Generation of cumulative second harmonics of a planar wave in a dispersive medium is examined in this paper.Analytical expressions of cumulative second harmonic amplitude and phase with a simple form are derived.The critical distance of cumulative second harmonic generation is determined.With the presented analysis method it is easy to understand the physical process of generation of cumulative second harmonic in a dispersive medium.
