摘要：
Values for the electro-optic and second-harmonic-generation coefficients r41 and d14(SHG) can be calculated from absolute spontaneous-Raman-scattering data alone. The ratio of electronic and lattice contributions to r41, and the stimulated Raman gain coefficients for the LO and TO modes, may also be obtained. The technique is applied to GaAs and the value for r41 [(1.50.1)×10-12mV] agrees with direct measurements, while the value for d14(SHG) [(1.40.1)×10-10mV] is within the range of some direct SHG measurements. © 1969 The American Physical Society.
