Thus, the measurement and control of CEP is essential for applications of few-cycle lasers. Currently, there is no robust method for measuring the non-trivial spatial CEP distribution of few-cycle laser pulses. Here, we demonstrate a compact on-chip, ambient-air, CEP scanning probe with 0.1 µm 3 resolution based on optical driving of CEP-sensitive ultrafast currents in a metal−dielectric heterostructure. We successfully apply the probe to obtain a 3D map of spatial changes of CEP in the vicinity of an oscillator beam focus with pulses as weak as 1 nJ. We also demonstrate CEP control in the focal volume with a spatial light modulator so that arbitrary spatial CEP sculpting could be realized.}, year = {2023}, eissn = {2041-1723}, orcid-numbers = {Pápa, Zsuzsanna/0000-0003-3567-6468; Budai, Judit/0000-0001-9156-2233; Paul, Pallabi/0000-0003-2701-3189; Szeghalmi, Adriana/0000-0003-2055-2825; Dombi, Péter/0000-0002-0736-3512} } @article{MTMT:33062901, title = {Spot size dependence of the ablation threshold of BK7 optical glass processed by single femtosecond pulses}, url = {https://m2.mtmt.hu/api/publication/33062901}, author = {Andrásik, Attila and Budai, Judit and Szörényi, Tamás and Vass, Csaba and Flender, Roland and Hopp, Béla}, doi = {10.1007/s00339-023-06782-z}, journal-iso = {APPL PHYS A-MATER}, journal = {APPLIED PHYSICS A - MATERIALS SCIENCE AND PROCESSING}, volume = {129}, unique-id = {33062901}, issn = {0947-8396}, year = {2023}, eissn = {1432-0630}, orcid-numbers = {Budai, Judit/0000-0001-9156-2233; Szörényi, Tamás/0000-0002-8888-4167; Vass, Csaba/0000-0003-1443-3360; Flender, Roland/0000-0001-6970-0716; Hopp, Béla/0000-0002-4272-7721} } @article{MTMT:33240100, title = {Ultrasensitive probing of plasmonic hot electron occupancies}, url = {https://m2.mtmt.hu/api/publication/33240100}, author = {Budai, Judit and Pápa, Zsuzsanna and Petrik, Péter and Dombi, Péter}, doi = {10.1038/s41467-022-34554-5}, journal-iso = {NAT COMMUN}, journal = {NATURE COMMUNICATIONS}, volume = {13}, unique-id = {33240100}, issn = {2041-1723}, abstract = {Non-thermal and thermal carrier populations in plasmonic systems raised significant interest in contemporary fundamental and applied physics. Although the theoretical description predicts not only the energies but also the location of the generated carriers, the experimental justification of these theories is still lacking. Here, we demonstrate experimentally that upon the optical excitation of surface plasmon polaritons, a non-thermal electron population appears in the topmost domain of the plasmonic film directly coupled to the local fields. The applied all-optical method is based on spectroscopic ellipsometric determination of the dielectric function, allowing us to obtain in-depth information on surface plasmon induced changes of the directly related electron occupancies. The ultrahigh sensitivity of our method allows us to capture the signatures of changes induced by electron-electron scattering processes with ultrafast decay times. These experiments shed light on the build-up of plasmonic hot electron population in nanoscale media.}, year = {2022}, eissn = {2041-1723}, orcid-numbers = {Budai, Judit/0000-0001-9156-2233; Pápa, Zsuzsanna/0000-0003-3567-6468; Petrik, Péter/0000-0002-5374-6952; Dombi, Péter/0000-0002-0736-3512} } @{MTMT:33188471, title = {On-Chip Carrier-Envelope Phase Scanner}, url = {https://m2.mtmt.hu/api/publication/33188471}, author = {Hanus, Václav and Fehér, Beatrix and Pápa, Zsuzsanna and Budai, Judit and Paul, P. and Szeghalmi, A. and Dombi, Péter}, booktitle = {Proceedings Conference on Lasers and Electro-Optics - Part of CLEO: 2022}, doi = {10.1364/CLEO_SI.2022.SS2A.2}, unique-id = {33188471}, year = {2022}, orcid-numbers = {Pápa, Zsuzsanna/0000-0003-3567-6468; Budai, Judit/0000-0001-9156-2233; Dombi, Péter/0000-0002-0736-3512} } @article{MTMT:33174692, title = {Femtosecond Control of Plasmonic Field Enhancement by Mode-mixing}, url = {https://m2.mtmt.hu/api/publication/33174692}, author = {Pápa, Zsuzsanna and Sándor, Péter and Lovász, Béla and Budai, Judit and Dombi, Péter and Rácz, Péter}, doi = {10.1364/UP.2022.W4A.31}, journal-iso = {OPTICS INFOBASE CONF PAP}, journal = {OPTICS INFOBASE CONFERENCE PAPERS}, volume = {2022}, unique-id = {33174692}, issn = {2162-2701}, year = {2022}, orcid-numbers = {Pápa, Zsuzsanna/0000-0003-3567-6468; Budai, Judit/0000-0001-9156-2233; Dombi, Péter/0000-0002-0736-3512; Rácz, Péter/0000-0001-5099-1031} } @article{MTMT:33163453, title = {Laser-Induced Ultrafast Currents in Dielectrics Enhanced by Iridium Nanoparticles}, url = {https://m2.mtmt.hu/api/publication/33163453}, author = {Fehér, Beatrix and Hanus, Václav and Pápa, Zsuzsanna and Budai, Judit and Paul, P. and Szeghalmi, A. and Dombi, Péter}, doi = {10.1364/HILAS.2022.HF3B.5}, journal-iso = {OPTICS INFOBASE CONF PAP}, journal = {OPTICS INFOBASE CONFERENCE PAPERS}, volume = {2022}, unique-id = {33163453}, issn = {2162-2701}, year = {2022}, orcid-numbers = {Pápa, Zsuzsanna/0000-0003-3567-6468; Budai, Judit/0000-0001-9156-2233; Dombi, Péter/0000-0002-0736-3512} } @article{MTMT:33163451, title = {On-Chip Carrier-Envelope Phase Scanner of Few-Cycle Oscillator Beams}, url = {https://m2.mtmt.hu/api/publication/33163451}, author = {Hanus, Václav and Fehér, Beatrix and Pápa, Zsuzsanna and Budai, Judit and Wang, Z. and Paul, P. and Szeghalmi, A. and Dombi, Péter}, doi = {10.1364/UP.2022.Th1A.2}, journal-iso = {OPTICS INFOBASE CONF PAP}, journal = {OPTICS INFOBASE CONFERENCE PAPERS}, volume = {2022}, unique-id = {33163451}, issn = {2162-2701}, year = {2022}, orcid-numbers = {Pápa, Zsuzsanna/0000-0003-3567-6468; Budai, Judit/0000-0001-9156-2233; Dombi, Péter/0000-0002-0736-3512} } @article{MTMT:33098755, title = {On-Chip Carrier-Envelope Phase Scanner}, url = {https://m2.mtmt.hu/api/publication/33098755}, author = {Hanus, Václav and Fehér, Beatrix and Pápa, Zsuzsanna and Budai, Judit and Paul, P. and Szeghalmi, A. and Dombi, Péter}, doi = {10.1364/HILAS.2022.HF3B.3}, journal-iso = {OPTICS INFOBASE CONF PAP}, journal = {OPTICS INFOBASE CONFERENCE PAPERS}, volume = {2022}, unique-id = {33098755}, issn = {2162-2701}, year = {2022}, orcid-numbers = {Pápa, Zsuzsanna/0000-0003-3567-6468; Budai, Judit/0000-0001-9156-2233; Dombi, Péter/0000-0002-0736-3512} }
