Abstract
Optical activity changes the refractive indices of a crystal, and these changes should be taken into account when calculating the phase-matching angles. A method for calculating this change in refractive indices is presented and the effects on the phase-matching direction in KTiOPO(4) are shown. Although, in this case, the change is small, it may be considerably larger in other crystals.
摘要
旋光性会改变晶体的折射率，在计算相位匹配角时应考虑这些变化。本文提出了一种计算折射率变化的方法，并展示了其对磷酸钛氧钾（KTiOPO₄）中相位匹配方向的影响。尽管在这种情况下变化很小，但在其他晶体中可能会大得多。
