双相位共轭镜的工作条件参数分析

Analysis of the Performance Parameters of a Double Phase Conjugate Mirror(DPCM)

本文讨论了纯扩散机制的光折变晶体用作单作用区的双相位共轭镜（ＤＰＣＭ）时的阈值耦合强度和允许的输入光强比范围，并与双作用区的情况进行比较后，给出了在输入光强比远离１的条件下，双相位共轭镜的正常工作的条件参数。

In this paper the threshold coupling strength and the maximum perndttable optical powerratio of DPCM with single interacting region for optical refractive cryStal of pure damsion mwhanism arediscussed. The results are compared with those of another type of DPCM which consists of tab interactingregions. If q X 1 or q X l, the performance parameters of DPCM with any interacting regions are given.
