Abstract

A full-phase measurement of low-energy femtosecond UV pulses is presented. The method relies on phase retrieval of measured sonogram traces and is greatly simplified by a two-dimensional shaper-assisted cross correlation setup. As all required pulses are generated by the pulse shaper, the method is free of external references and additional tunable filter setups.

Schematic overview of UV phase measurement by shaper-assisted sonogram acquisition. (a) The principle of measurement relies on a cross correlation between a spectrally filtered replica of the pulse and the pulse itself. (b) A 2D shaper with a diffraction pattern enables simplified generation of these two pulses. (c) The shaper, together with a two-photon absorption correlator, allows sensitive and simple sonogram acquisition.

Characterization of a TL pulse with different filter bandwidths. (a) Two retrievals of the spectral phase from a transform limited pulse with two different filters at around 50% and 25% of the FWHM pulse bandwidth, respectively. The bandwidths yield similar results, as is especially visible in (b) comparison of the autocorrelation data. The inset shows the comparison between retrieved and experimental given filter bandwidths. For the 3.3 THz filter, its bandwidth is accurately reconstructed.

Phase retrieval of chirped pulses. (a) Raw data sonograms (filter: 6.6 THz ), in contrast to SHG FROG data, the sign of the chirp is unambiguously visible. (b) Processed measured sonograms (baseline corrected, lowpass filtered, interpolated). (c) Sonograms retrieved by PCGPA algorithm. (d) Retrieved spectral phase shows good agreement with given chirp parameter shown in (a).
