| Abstract: | The measurement of nonlinear refractive index with Z-scan method for slow decay materials are discussed in detail. We derive the resultant electric field pattern at the aperture. It is pointed out that the accumulating effect contribute largely to the Z-scan signal in the slow decay nonlinear optical materials. The theoretical analysis is consistent with experimental result. |
