摘要:	摘要： We demonstrate that temporally-dependent polarization states of ultrashort laser pulses can be reconstructed in a single shot by use of an angle-multiplexed spatial-spectral interferometry. This is achieved by introducing two orthogonally polarized reference pulses and interfering them with an arbitrarily polarized ultrafast pulse under measurement. A unique calibration procedure is developed for this technique which facilitates the subsequent polarization state measurements. The accuracy of several reconstructed polarization states is verified by comparison with that obtained from an analytic model that predicts the polarization state on the basis of its method of production. Laser pulses with mJ-level energies were characterized via this technique, including a time-dependent polarization state that can be used for polarization-gating of high-harmonic generation for production of attosecond pulses. 其他題名： Sci Rep 出版者： London: Nature Publishing Group UK 出版日期： 2016-09-06 出處： Scientific reports, 2016-09, Vol.6 (1), p.32839-32839, Article 32839 資源來源： Springer Nature Open Access Journals 版權： The Author(s) 2016 版權： Copyright Nature Publishing Group Sep 2016 版權： Copyright © 2016, The Author(s) 2016 The Author(s) 識別號： ISSN: 2045-2322 識別號： EISSN: 2045-2322 識別號： DOI: 10.1038/srep32839 識別號： PMID: 27596951
