转角相位匹配实现亚相干长度非线性光学调控

Science Bulletin 2024年第9期69卷 1170-1172页

As recognized since the very early age in the 1960s [1], phase matching is always the crucial problem throughout the development of the nonlinear optics up to date. This problem of the phase mismatch is raised as result of material dispersion inside a nonlinear crystal, from the momentum conservation in the optical nonlinear interaction process. In the case of the second harmonic(SH) generation, for example, the momentum of an SH photon is normally not matched to the sum of the momenta of the two fundamental beam photons, due to their different refractive indexes.
