The laser pulse duration at the two wavelengths were 40 and 190 fs. The peak intensity inside the crystals varied between approximately 110 and 550 GW/cm 2 . The 3 PA and 4 PA coefficients were evaluated using a theoretical model and the results suggest that their minima are at or around the Mg doping level corresponding to the threshold for suppressing photo-refraction for both cLN and sLN. This result can be attributed to the contribution of crystal defects to the 3 PA and 4 PA processes. Furthermore, the 4 PA at 1030 nm exhibited greater nonlinear absorption than the 3 PA at 800 nm under the same intensity level. Possible reasons for this unexpected behavior are discussed. Overall, comparing the 3 PA and 4 PA values of these crystals will enable for selection of the optimum composition of LN crystal for efficient THz generation and for other nonlinear optical processes requiring high pump intensities.}, year = {2024}, pages = {7030-7043}, orcid-numbers = {Rácz, Péter/0000-0001-5099-1031; Dombi, Péter/0000-0002-0736-3512} } @article{MTMT:34576933, title = {Controlling Plasmonic Field Enhancement via the Interference of Orthogonal Plasmonic Modes}, url = {https://m2.mtmt.hu/api/publication/34576933}, author = {Bánhegyi, Balázs and Tóth, Lázár and Dombi, Péter and Budai, Judit and Hanus, Václav and Rácz, Péter and Pápa, Zsuzsanna}, doi = {10.1007/s11468-024-02212-9}, journal-iso = {PLASMONICS}, journal = {PLASMONICS}, unique-id = {34576933}, issn = {1557-1955}, abstract = {Optical nanoantennas concentrate light into their local fields. The field concentration property is governed by the plasmonic resonances and their interference. Here, we present a method for controllable local-field interferences in the hot spot of nanorods and experimentally demonstrate that the field enhancement can be tuned in a wide range. For this, we design nanoparticles with given phase relations between their plasmonic eigenmodes and at the same time tune the phase between the components of the external field by changing its polarization state to achieve in-phase excitation of the plasmon modes. Strong-field photoemission is applied to probe the field enhancement property of the nanorods employing femtosecond pulses of different polarization states. Our findings provide a new degree of freedom in plasmonic resonance tuning and may inspire diverse designs of local-field responses and expand the applications in nanoscale sensing, spectroscopy, and dynamically tunable devices.}, year = {2024}, eissn = {1557-1963}, orcid-numbers = {Dombi, Péter/0000-0002-0736-3512; Rácz, Péter/0000-0001-5099-1031; Pápa, Zsuzsanna/0000-0003-3567-6468} } @article{MTMT:34516670, title = {Interjú Kroó Norberttel}, url = {https://m2.mtmt.hu/api/publication/34516670}, author = {Dombi, Péter}, journal-iso = {FIZIKAI SZEMLE}, journal = {FIZIKAI SZEMLE}, volume = {74}, unique-id = {34516670}, issn = {0015-3257}, year = {2024}, pages = {24-26}, orcid-numbers = {Dombi, Péter/0000-0002-0736-3512} } @article{MTMT:34512834, title = {Krausz Ferenc – magyar Nobel-díj az extrém nemlineáris optikáért}, url = {https://m2.mtmt.hu/api/publication/34512834}, author = {Dombi, Péter}, journal-iso = {FIZIKAI SZEMLE}, journal = {FIZIKAI SZEMLE}, volume = {74}, unique-id = {34512834}, issn = {0015-3257}, year = {2024}, pages = {16-19}, orcid-numbers = {Dombi, Péter/0000-0002-0736-3512} } @article{MTMT:34512550, title = {Krausz Ferenc Nobel-díja és a kapcsolódó hazai kutatások}, url = {https://m2.mtmt.hu/api/publication/34512550}, author = {Dombi, Péter}, journal-iso = {FIZIKAI SZEMLE}, journal = {FIZIKAI SZEMLE}, volume = {74}, unique-id = {34512550}, issn = {0015-3257}, year = {2024}, pages = {1-1}, orcid-numbers = {Dombi, Péter/0000-0002-0736-3512} } @article{MTMT:34549160, title = {Az atomok világának kapujában.
