摘要
通过对纳米微晶表面态的考虑,运用三能级的密度矩阵方程导出了三阶非线性光学电极化率.进而,详细讨论了纳米微晶表面态对三阶非线性电极化率的影响.
Third Power nonlinear optical susceptibility of nanometer materials was deduced through consideration of surface states of nano crystallites and using density matrix equation of three level system.Furthermore,the nonlinear optical properties affected by the surface states of nano crystallites were discussed in detail.
