Therefore, complete security analysis of implementations of QKD protocols is in the focus of interest of a worldwide information-security community. For today, a number of QKD loopholes are closed by countermeasures, which are also considered in emerging QKD security evaluation and certification [1-3]. However, new threats to practical QKD implementations are still found, such as the laser-damage attack, which is a powerful hacking strategy. In investigations, CW laser radiation is most often used, but in contrast to it, the interaction of pulsed laser radiation with optical materials may lead to a wide range of effects, like nonlinear effects, dielectric breakdown, etc.Materials ScienceResilience of Quantum Key Distribution Source against Laser-Damage Attack by a Variety of LasersConference PaperSCOPUS10.1109/CLEO/EUROPE-EQEC57999.2023.102316032-s2.0-85175692991
