Abstract
Z-scan measurement with a slit instead of a circular aperture is proposed and analyzed for an astigmatic Gaussian beam. This new technique can accurately determine not only the nonlinear refractive index but also the ellipticity and positions of x-y foci of the astigmatic beam. © 2000 Optical Society of America.
