The change of quartz crystal refractive index is measured under the different outside force, and the elasto-optical coefficient is determined.
通过测量石英晶体在不同的外力下折射率的变化情况，确定了晶体的弹光系数。

We also investigate the influence of the piezoelectric and elasto-optic effect on the optimum gain for (110), (111), (112) and their equivalent cuts.
还讨论了压电和弹光效应对（110），（111）及（112）切割面优化增益的影响。
