dc.description.abstract
We explore the capabilities of metallic spintronic thin-film stacks as a
source of intense and broadband terahertz electromagnetic fields. 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.
