为了解决二次谐波(SHG)法和参数荧光法之间存在的较大差异，我们首次用参数荧光法和差频测量法重新测定了LiNbO_3的非线性光学系数d31的绝对值。我们得到d31=4.8。5和4.3。在泵浦波长分别为488 nm和532 nm时，输出功率为5 pm/V，与倍频数据吻合较好。以前的参数荧光值d31=5.8 pm/V似乎被高估了。
We have redetermined the absolute values of the nonlinear optical coefficient, d 31, of LiNbO 3 by parametric fluorescence and, for the first time, by difference frequency generation measurements to resolve the considerable discrepancy that existed between the values determined by second-harmonic generation (SHG) and parametric fluorescence. We obtain d 31= 4.8. 5 and 4.3. 5 pm/V at the pump wavelengths of 488 and 532 nm, respectively, in reasonable agreement with the SHG data. It appears that the previous parametric fluorescence value, d 31= 5.8 pm/V, was overestimated.
