Abstract

The photorefractive beam coupling technique, also known as induced grating autocorrelation (IGA), was used to measure intensity independent refractive index (n2) in short lengths of fibers. The time delay was varied between two ultrashort excitation pulses, that formed a photorefractive grating, to produce the IGA trace. The diffracted intensity of the probe pulse was plotted against relative delay (τ).
