用单束和双束激发方法测量了CuCl中激子分子在双光子激发下的双极化子共振散射。发现了若干条散射线，其峰值能量不仅与观测方向密切相关，而且与两束激发激光束的几何构型密切相关。详细研究了入射能量和激发功率对这些散射线的峰值能量、线宽和极化的影响，发现了与巨双光子吸收相关的极化子色散的非线性影响。
Two polariton scattering in resonance with giant two-photon excitation of excitonic molecule in CuCl has been measured in various scattering configurations with using single-beam and two-beam excitation methods. Several scattering lines are found, the peak energies of which depend strongly not only on the direction of observation but also on the geometrical configuration of two excitation laser beams. Dependence of the peak energy, line width and polarization of these scattering lines upon the incident energy and the excitation power has been investigated in details, from which the non-linear effect on the polariton dispersion associated with the giant two-photon absorption is found.
