Abstract
A novel method for measuring the beam quality of short, powerful laser pulses is presented. It is based on the Z-scan technique used to investigate the nonlinear susceptibilities of optical materials. We show that both two-photon absorption and nonlinear refraction of a nonlinear sample can be used to obtain information about the spatial quality of the pulses.
