Abstract

Detection of second-order autocorrelations using two-photon absorption in semiconductors can have several advantages over the older technique where the autocorrelation using second-harmonic generation is recorded. Several commercial light-emitting diodes (LED) have a quadratic response to the pulse intensity of a Ti:sapphire laser. We report that they are suitable and smart detectors for sensitive measurements of sub-15-fs laser pulses and for qualitative estimations of pulse compression.
