Spatiotemporal amplitude and phase retrieval of Bessel-X pulses using a Hartmann-Shack sensor

Opt Express. 2009 Jun 8;17(12):9804-9. doi: 10.1364/oe.17.009804.

Abstract

We propose a new experimental technique, which allows for a complete characterization of ultrashort optical pulses both in space and in time. Combining the well-known Frequency-Resolved-Optical-Gating technique for the retrieval of the temporal profile of the pulse with a measurement of the near-field made with an Hartmann-Shack sensor, we are able to retrieve the spatiotemporal amplitude and phase profile of a Bessel-X pulse. By following the pulse evolution along the propagation direction we highlight the superluminal propagation of the pulse peak.
