20.500.12556/RUL-127277 High-sensitivity, simple frequency-resolved-optical-gating device We introduce a practical self-referenced device for the complete temporal intensity-and-phase measurement of fewfemtojoule-level fs and ps pulses based on the simple version of frequency-resolved-optical gating, called GRENOUILLE. We replace the usual crossed-beam line-focus geometry with a pointfocus near-collinear-beam geometry and a traditional delay line that allows a longer path length in the nonlinear medium, yielding greater sensitivity. As an initial demonstration of the device, we measured moderately complex pulses at energies as weak as 24 fJ with high signal-to-noise ratio. We confirmed the results measured using our technique to that of a standard GRENOUILLE and a high-resolution spectrometer. ultrafast optics ultrafast measurements frequency-resolved optical gating GRENOUILLE ultrahitra optika ultrakratki laserski pulzi spektralno razločena avtokorelacija true false true Angleški jezik Slovenski jezik Članek v reviji 2021-06-01 15:29:10 2021-06-01 15:29:16 2025-03-12 14:17:47 0000-00-00 00:00:00 2020 0 0 Str. 1-6 iss. 3, art. 8600306 Vol. 56 Jun. 2020 0000-00-00 PostprintKoncna Objavljeno NiDoloceno 2019-12-18 2020-04-02 2020-04-19 535(045) 0018-9197 10.1109/JQE.2020.2988653 16641283 RAZ_Jones_Travis_2020.pdf RAZ_Jones_Travis_2020.pdf 1 5CEE421453CB45A5BBA00216126E0B2F 6f7455dded97320d8aab4060b36fc029b64cf964ce9ce995447cbbd039007770 afbec320-c2e0-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=143601 https://ieeexplore.ieee.org/document/9072099 1 4ab6a89b-c2dd-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=143600 Fakulteta za strojništvo 0 0 0
