Abstract
The results of a theoretical analysis of the off-axis Z-scan method for measuring nonlinear refraction are presented. The dependences of the normalized transmittance are calculated for different radii and positions of the aperture. The amplitude T pv and the distance between the maximum and the minimum Z pv are analyzed as functions of the aperture size.
