Universidad de Zaragoza (orcid)0000-0002-6048-310X Single-shot d-scan technique for ultrashort laser pulse characterization using transverse second-harmonic generation in random nonlinear crystals 2020 Access copy available to the general public Unrestricted We demonstrate a novel dispersion-scan (d-scan) scheme for single-shot temporal characterization of ultrashort laser pulses. The novelty of this method relies on the use of a highly dispersive crystal featuring antiparallel nonlinear domains with a random distribution and size. This crystal, capable of generating a transverse second-harmonic signal, acts simultaneously as the dispersive element and the nonlinear medium of the d-scan device. The resulting in-line architecture makes the technique very simple and robust, allowing the acquisition of single-shot d-scan traces in real time. The retrieved pulses are in very good agreement with independent frequency-resolved optical grating measurements. We also apply the new single-shot d-scan to a terawatt-class laser equipped with a programmable pulse shaper, obtaining an excellent agreement between the applied and the d-scan retrieved dispersions. info:eu-repo/grantAgreement/EUR/ERC/SISCAN-78992 info:eu-repo/grantAgreement/ES/MINECO/EQC2018-004117-P info:eu-repo/grantAgreement/ES/MINECO/FIS2017-87970-R info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 3.776 2020 OPTICS 22 / 99 = 0.222 2020 Q1 T1 1.524 2020 Atomic and Molecular Physics, and Optics 2020 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Alonso, B.
