Based on the Huygens-Fresnel diffraction integral method, we study the characteristics of the closed-aperture Z-scan traces. Most importantly, we present the analytical formulae of the closed-aperture Z-scan transmittance with simultaneous Kerr effect and n-photon absorption. Besides, we demonstrate that the determination of the third-order nonlinear refractive index in multiphoton absorbers becomes timesaving yet unambiguously by the presented theory. © 2010 Optical Society of America.||Source Title:||Journal of the Optical Society of America B: Optical Physics||URI:||http://scholarbank.nus.edu.sg/handle/10635/96202||ISSN:||07403224||DOI:||10.1364/JOSAB.27.002438|
