Paper Abstract

We present a single shot method of measurement of the nonlinear refractive index of materials. In this method a single laser pulse is used in a setup similar to the Z-scan technique. It is therefore as simple and sensitive as the z- scan. In this method unlike the Z-scan, the sample is fixed with respect to the lens while the focus position is scanned across the sample (F-scan). The far field transmission of the beam through an aperture is then measured. This method eliminates the need to move the sample in addition to the measurement error due to peak power fluctuations from pulse to pulse.
