摘要：

We have studied experimentally, by using a titanium sapphire laser, two-photon resonant effect of hyper-Raman scattering by optic phonons in 90-degrees scattering geometry for a ZnSe crystal. We have found a striking enhancement of the signal in resonance with the 2P excitonic state. From comparison of the result with the relevant two-photon absorption data, the present phenomenon can be interpreted in terms of the time-dependent perturbation formalism.
