For this purpose, we excite a W/CoFeB/Pt trilayer (thickness of 5.6 nm) on a large-area glass substrate (diameter of 7.5 cm) by a femtosecond laser pulse (energy 5.5 mJ, duration 40 fs, and wavelength 800 nm). After focusing, the emitted terahertz pulse is measured to have a duration of 230 fs, a peak field of 300 kV cm−1, and an energy of 5 nJ. In particular, the waveform exhibits a gapless spectrum extending from 1 to 10 THz at 10% of its amplitude maximum, thereby facilitating nonlinear control over matter in this difficult-to-reach frequency range on the sub-picosecond time scale.","5 Seiten","62131","https://refubium.fu-berlin.de/handle/fub188/20865||http://dx.doi.org/10.17169/refubium-24164","eng","http://publishing.aip.org/authors/web-posting-guidelines","500 Naturwissenschaften und Mathematik::530 Physik","Ultrabroadband single-cycle terahertz pulses with peak fields of 300 kV cm−1 from a metallic spintronic emitter","Wissenschaftlicher Artikel","open access","Applied Physics Letters. - 110 (2017), 25, Artikel Nr. 252402","10.1063/1.4986755","http://dx.doi.org/10.1063/1.4986755","0003-6951","Institut für Experimentalphysik:::0e15dd66-95f1-40d5-8307-e68203f86a76:::600","Physik","FUDOCS_derivate_000000009655","FUDOCS_document_000000029610","no"
