High order Brunel harmonics and supercontinuum formed by a weak optical pump in presence of a strong terahertz field
Ihar Babushkin, Ayhan Demircan, Uwe Morgner +1
Brunel harmonics appear in the optical response of an atom in process of laser-induced ionization, when the electron leaves the atom and is accelerated in the strong optical field.…
Metallic nanostructures as electronic billiards for nonlinear terahertz photonics
Ihar Babushkin, Liping Shi, Ayhan Demircan +3
Optical properties of metallic nanoparticles are most often considered in terms of plasmons, the coupled states of light and quasi-free electrons. Here we predict that confinement…
Dynamic focus shaping with mixed-aperture coherent beam combining
Maike Prossotowicz, Daniel Flamm, Andreas Heimes +5
A novel concept for dynamic focus shaping based on highly efficient coherent beam combining with microlens arrays (MLA) as combining element is presented. This concept allows to co…
