Tracking ultrafast photocurrents in the Weyl semimetal TaAs using THz emission spectroscopy
N. Sirica, R. I. Tobey, L. X. Zhao +14
We investigate polarization-dependent ultrafast photocurrents in the Weyl semimetal TaAs using terahertz (THz) emission spectroscopy. Our results reveal that highly directional, tr…
Probing and controlling terahertz-driven structural dynamics with surface sensitivity
P. Bowlan, J. Bowlan, S. A. Trugman +8
Intense, single-cycle terahertz (THz) pulses offer a promising approach for understanding and controlling the properties of a material on an ultrafast time scale. In particular, re…
Probing ultrafast spin dynamics in the antiferromagnetic multiferroic HoMnO through a magnon resonance
P. Bowlan, S. A. Trugman, J. Bowlan +5
We demonstrate a new approach for directly measuring the ultrafast energy transfer between elec- trons and magnons, enabling us to track spin dynamics in an antiferromagnet (AFM).…
Measuring the spatio-temporal field of diffracting ultrashort pulses
P. Bowlan, M. Lohmus, P. Piksarv +3
Using SEA TADPOLE, we directly measure the spatio-temporal field of diffracting ultrashort pulses with femtosecond temporal and micrometer spatial resolutions. Using a circular ape…
Directly measuring the spatiotemporal electric field of ultrashort Bessel-X pulses
P. Bowlan, R. Trebino, H. Valtna-Lukner +3
Using SEA TADPOLE with micrometer-range spatial and femtosecond-range temporal resolution, we report the first direct spatiotemporal measurements of ultrashort Bessel-X pulses. We…
Shaped pulse electric-field construction and interferometric characterization: The SPECIFIC method
Matthew A. Coughlan, Mateusz Plewicki, Stefan M. Weber +3
A method is reported for creating, generating, and measuring parametrically shaped pulses for time-bandwidth product >>5, which consists of a parametric pulse-shaping algorithm, a…
