In our calculations we used linearly polarised ultrashort 7 fs laser pulses, 6.5 \times 10^{14} \mathrm {W/cm^{2}} 6.5 × 10 14 W / cm 2 intensity, and a central wavelength of 800 nm. Our results show that electrons with the highest kinetic energies are obtained with transform limited (TL) pulses. The shaping of the pulses with negative second- third- or fourth- order dispersion results in higher ionisation yield and electron energies compared to pulses shaped with positive dispersion values. We have also investigated how the Carrier Envelope Phase (CEP) dependence of the ionisation is infuenced by dispersion. We calculated the left-right asymmetry as a function of energy and CEP for sodium atoms employing pulses of 4.5 fs, 800 nm central wavelength, and 4 \times 10^{12}\mathrm {W/cm^{2}} 4 × 10 12 W / cm 2 intensity. We found that the left-right asymmetry is more pronounced for pulses shaped with positive Group Delay Dispersion (GDD). It was also found that shaping a pulse with increasing amounts of GDD in absolute value blurs the CEP dependence, which is attributed to the increasing number of optical cycles.}, year = {2022}, eissn = {2045-2322}, orcid-numbers = {Márton, István/0000-0001-7024-8245} } @article{MTMT:32758425, title = {Understanding the mechanisms of L-shell x-ray emission from Os atoms bombarded by 4-6 MeV/u fluorine ion}, url = {https://m2.mtmt.hu/api/publication/32758425}, author = {Chatterjee, S. and Kumar, S. and Kumar, S. and Oswal, M. and Mohanty, B. and Mehta, D. and Mitra, D. and Mendez, A.M.P. and Mitnik, D.M. and Montanari, C.C. and Sarkadi, László and Nandi, T.}, doi = {10.1088/1402-4896/ac5711}, journal-iso = {PHYS SCR}, journal = {PHYSICA SCRIPTA}, volume = {97}, unique-id = {32758425}, issn = {0031-8949}, year = {2022}, eissn = {1402-4896} } @article{MTMT:32096507, title = {Comparative study of classical theoretical descriptions of the ionization of atoms induced by few-cycle laser pulses}, url = {https://m2.mtmt.hu/api/publication/32096507}, author = {Sarkadi, László}, doi = {10.1103/PhysRevA.103.053113}, journal-iso = {PHYS REV A}, journal = {PHYSICAL REVIEW A}, volume = {103}, unique-id = {32096507}, issn = {2469-9926}, year = {2021}, eissn = {2469-9934}, orcid-numbers = {Sarkadi, László/0000-0002-5763-2063} } @article{MTMT:31642985, title = {Dissociative multiple ionization of the H2O molecule induced by ion impact: experimental and theoretical results}, url = {https://m2.mtmt.hu/api/publication/31642985}, author = {Kovács, Sándor and Herczku, Péter and Juhász, Zoltán and Sarkadi, László and Gulyás, László and Chesnel, J-Y and Sulik, Béla}, doi = {10.1088/1742-6596/1412/15/152071}, journal-iso = {J PHYS CONF SER}, journal = {JOURNAL OF PHYSICS-CONFERENCE SERIES}, volume = {1412}, unique-id = {31642985}, issn = {1742-6588}, year = {2020}, eissn = {1742-6596} } @article{MTMT:31396030, title = {Laser-induced nonsequential double ionization of helium: classical model calculations}, url = {https://m2.mtmt.hu/api/publication/31396030}, author = {Sarkadi, László}, doi = {10.1088/1361-6455/ab9764}, journal-iso = {J PHYS B AT MOL OPT PH}, journal = {JOURNAL OF PHYSICS B: ATOMIC MOLECULAR AND OPTICAL PHYSICS}, volume = {53}, unique-id = {31396030}, issn = {0953-4075}, year = {2020}, eissn = {1361-6455}, pages = {165401} } @article{MTMT:30689524, title = {Dissociative ionization of the H 2 O molecule bombarded by swift singly charged and slow highly charged ions}, url = {https://m2.mtmt.hu/api/publication/30689524}, author = {Kovács, Sándor and Herczku, Péter and Juhász, Zoltán and Sarkadi, László and Gulyás, László and Chesnel, Jean Yves. and Ábrók, Levente and Frémont, Francois and Hajaji, Anas and Sulik, Béla}, doi = {10.1002/xrs.3072}, journal-iso = {X-RAY SPECTROM}, journal = {X-RAY SPECTROMETRY}, volume = {49}, unique-id = {30689524}, issn = {0049-8246}, year = {2020}, eissn = {1097-4539}, pages = {133-137}, orcid-numbers = {Kovács, Sándor/0000-0001-5332-3901} }
