摘　　要：本文基于部分相于光理论重新考察并描述了晶体的倍频过程．概括地说，本文用人射基波传播经基矢为ａ、ｂ的晶格定义出晶体输出面中两点ｐ２和Ｐ１，然后计算该两点２ω０光振动分量之间的互相干函数，在互相千函数的计算中采用了频域变换技术，通过引人定义量Ｐ（ω）及其求解，最后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描述．The frequency doubling process in crystal has been reconsidered based on the theory of partial coherence in this paper. Two point P2 and P1 in the exit plane of the crystal is defined by the incident fundamental wave passing through lattice of which the primitive vectors are a and b respectively. Then the mutual coherence function of the light vibration at this two points at the frequency 2ω0 is calculated with the transformation technique in the frequency domain. Through introducing the definition p(ω) and its solution, the theoretical description of distribution of radiant intensity of the second harmonic wave excited by the incident fundamental wave based on the theory of partial coherence is finally obtained.
