Single photon zeptosecond interferometry
Geoffrey R. Harrison, Tobias Saule, R. Esteban Goetz +6
We demonstrate the generation of a train of attosecond XUV pulses that are in a superposition of wavefront states. Such superposition yields a high precision, self-referencing, com…
Optical Vortices: Revolutionizing the field of linear and nonlinear optics
Bikash K. Das, Camilo Granados, Marcelo F. Ciappina
Light is the fundamental medium through which we perceive the world around us. In the modern era, light can not only be used in its raw form but can also be used as a versatile too…
A spatiotemporal couplings perspective on harmonic vortices generation
C. Granados, B. Kumar Das, M. F. Ciappina +1
The interaction of light with matter serves as a fundamental tool for probing material properties across a wide range of energy regimes. Recent breakthroughs in tailoring the topol…
The role of spatiotemporal couplings in harmonic vortex generation
C. Granados, Bikash K. Das, M. Ciappina +1
We explore the impact of spatiotemporal couplings (STCs) on high-order harmonic generation (HHG) driven by spatiotemporal vortex beams. Our investigation demonstrates how STCs shap…
Attosecond vortices in semiconductor materials
C. Granados, B. Kumar Das, Christian Heide +2
We present the first theoretical results on the generation of short-wavelength attosecond vortex beams in semiconductors through their interactions with an intense Laguerre-Gauss b…
High-Order Harmonic Generation Driven by Perfect Optical Vortex Beams: Exploring the Orbital Angular Momentum Upscaling Law
Bikash Kumar Das, C. Granados, M. Krüger +1
Orbital angular momentum (OAM) light beams for high-order harmonic generation (HHG) provide an additional degree of freedom to study the light-matter interaction at ultrafast times…
