Theory of plasmon-enhanced high-harmonic generation in the vicinity of metal nanostructures in noble gases
A. Husakou, S. -J. Im, J. Herrmann
We present a semiclassical model for plasmon-enhanced high-harmonic generation (HHG) in the vicinity of metal nanostructures. We show that both the inhomogeneity of the enhanced lo…
Generation of terahertz radiation from ionizing two-color laser pulses in Ar filled metallic hollow waveguides
I. Babushkin, S. Skupin, J. Herrmann
The generation of THz radiation from ionizing two-color femtosecond pulses propagating in metallic hollow waveguides filled with Ar is numerically studied. We observe a strong resh…
Magnetic imaging of superconducting qubit devices with scanning SQUID-on-tip
E. Marchiori, L. Ceccarelli, N. Rossi +6
We use a scanning superconducting quantum interference device (SQUID) to image the magnetic flux produced by a superconducting device designed for quantum computing. The nanometer-…
Ultrafast spatio-temporal dynamics of terahertz generation by ionizing two-color femtosecond pulses in gases
I. Babushkin, W. Kuehn, C. Koehler +6
We present a combined theoretical and experimental study of spatio-temporal propagation effects in terahertz (THz) generation in gases using two-color ionizing laser pulses. The ob…
Tailoring THz radiation by controlling tunnel photoionization events in gases
I. Babushkin, S. Skupin, A. Husakou +4
Applications ranging from nonlinear terahertz spectroscopy to remote sensing require broadband and intense THz radiation which can be generated by focusing two-color laser pulses i…
High-power supercontinuum generation in dielectric-coated metallic hollow waveguides
A. Husakou, J. Herrmann
In this Letter we theoretically study a novel approach for soliton-induced supercontinuum generation based on the application of metallic dielectric-coated hollow waveguides. Low l…
