【摘要】 文献［２］中关于倍频的部分相干光理论。Ⅰ．定义与描述，基于部分相干光理论重新考察并锚述了晶体的倍频过程，从而最终确定了由部分相干光理论所重新表述的入射基波激励产生的二次谐波的辐射强度分布的理论锚述．但是我们也许会问是否有可能证明：文章中抽象定义的采用，以及从这种引入的抽象定义并辅以部分相干光理论论证可行性的要求出发得到的结果确实是合理的．本文将探讨推理思路与先前Ｆｒａｎｋｅｎ和Ｗａｒｄ的描述［１］是否一致，并进一步看到这种定义以及基于这种定义所展开的论证是否成立．更多还原

【Abstract】 The frequency doubling process in crystal has been reconsidered based on the theory of partial coherence in the manuscript the coherence theory concerning the frequency doubling:Ⅰ. definition and description, and the theoretical description of distribution of radiant intensity of the second harmonic wave excited by the incident fundamental wave is finally expressed afresh by the theory of partial coherence. But we may ask whether we might not prove the validity of the result obtained from such abstract idea supplemented by the requirement of demonstrating feasibility of the theory of partial coherence. The author will inquire into the consistency in this contribution between the line of reasoning in the above paper with the former description of the Franken and Ward, and furthermore we see whether the definition and the demonstration based on it are tenable or not.更多还原
