金刚石是宽禁带半导体，具有优良的物理和化学性质；因此，它们被认为是非常适合光电器件的材料。基于克尔效应，我们介绍了一种简单可行的测量人造金刚石三阶非线性光学磁化率的方法。在实验中，使用了合成 I 型金刚石样品和横向电光调制系统。对于波长为650 nm的激光，分别在ε(3)1212=2：17×10-23 m2=V2和S44=1.93×10-23 m2=V2时得到金刚石样品的三阶磁化率和克尔系数。
Diamonds are wide-gap semiconductors possessing excellent physical and chemical properties; thus, they are regarded as very appropriate materials for optoelectronic devices. Based on the Kerr effect, we introduce a simple and feasible method for measuring the third-order nonlinear optical susceptibility of synthetic diamonds. In the experiments, synthetic type I diamond samples and transverse electro-optic modulation systems are utilized. As for the laser with the wavelength of 650 nm, the third-order susceptibility and Kerr coefficient of the diamond samples are obtained at ?(3)1212=2:17×10-23 m2=V2 and S44= 1.93×10-23 m2=V2, respectively.
