Vortex inverted pin beams: Mitigation of scintillations in strong atmospheric turbulence
Sotiris Droulias, Michalis Loulakis, Dimitris G. Papazoglou +3
We recently introduced a new class of optical beams with a Bessel-like transverse profile and increasing beam width during propagation, akin to an "inverted pin". Owing to their sp…
Inverted pin beams for robust long-range propagation through atmospheric turbulence
Sotiris Droulias, Michalis Loulakis, Dimitris G. Papazoglou +3
We introduce a new class of optical beams, which feature a spatial profile akin to an ``inverted pin''. In particular, we asymptotically find that close to the axis the transverse…
Transparent Multispectral Photonic Electrode for All-Weather Stable and Efficient Perovskite Solar Cells
George Perrakis, Anna C. Tasolamprou, George Kakavelakis +5
Perovskite solar cells (PSCs) are the most promising technology for advancing current photovoltaic performance. However, the main challenge for their practical deployment and comme…
Phase memory preserving harmonics from abruptly autofocusing beams
Anastasios D. Koulouklidis, Dimitris G. Papazoglou, Vladimir Yu. Fedorov +1
We demonstrate both theoretically and experimentally that the harmonics from abruptly auto-focusing ring-Airy beams present a surprising property, they preserve the phase distribut…
Generation of intense terahertz radiation by two-color filamentation of laser pulses with different wavelengths
Vladimir Yu. Fedorov, Stelios Tzortzakis
We theoretically study the generation of terahertz (THz) radiation by two-color filamentation of ultrashort laser pulses with different wavelengths. We consider wavelengths in the…
