利用分离光束法,我们测量了晶体GdCa4O(BO3)3和YCa4O(BO3)3的全二阶非线性光学张量。我们的 d 张量 (d = chi(2)/2) 与之前的报告不同,但对于 1064 nm 光的 I 型倍增给出了几乎相同的 d_eff 值。然而,对于其他波长或 II 型倍增,我们的张量给出的 d_eff 值与替代张量明显不同。
Using the separated-beam method, we have measured the full second-order nonlinear optical tensors of the crystals GdCa4O(BO3)3 and YCa4O(BO3)3. Our d tensors (d = chi(2)/2) differ from those of previous reports but give nearly the same values of d_eff for type-I doubling of 1064-nm light. However, for other wavelengths or for type-II doubling, our tensors give values for d_eff distinctly different from the alternative tensors.
