Compact realization of all-attosecond pump-probe spectroscopy
Martin Kretschmar, Evaldas Svirplys, Mikhail Volkov +4
The ability to perform attosecond-pump attosecond-probe spectroscopy (APAPS) is a longstanding goal in ultrafast science. While first pioneering experiments demonstrated the feasib…
Experimental control of quantum-mechanical entanglement in an attosecond pump-probe experiment
Lisa-Marie Koll, Laura Maikowski, Lorenz Drescher +2
Entanglement is one of the most intriguing aspects of quantum mechanics and lies at the heart of the ongoing Second Quantum Revolution, where it is a resource that is used in quant…

Peter Jürgens, Benjamin Liewehr, Björn Kruse +8
The formation of an electron-hole plasma during the interaction of intense femtosecond laser pulses with transparent solids lies at the heart of femtosecond laser processing. Advan…
Phase-Dependence of Resonant and Antiresonant Two-Photon Excitations
Lorenz Drescher, Tobias Witting, Oleg Kornilov +1
Measurements of the phase of two-photon matrix elements are presented for resonant and antiresonant two-color ionization of helium. A tunable, narrow-bandwidth, near-infrared (NIR)…
Phase cycling of extreme ultraviolet pulse sequences generated in rare gases

Many experiments in attosecond science will benefit from attosecond pulses at high repetition rates with sufficient photon flux for pump-probe experiments. We use 7fs, 800nm pulses…
Origin of strong-field induced low-order harmonic generation in amorphous solids
P. Jürgens, B. Liewehr, B. Kruse +8
Kerr-type nonlinearities form the basis for our physical understanding of nonlinear optical phenomena in condensed matter, such as self-focusing, solitary waves, and wave mixing. I…

With the emergence of high-repetition-rate few-cycle laser pulse amplifiers, aimed at investigating ultrafast dynamics in atomic, molecular and solid state science, the need for ev…
Extreme-ultraviolet refractive optics
Lorenz Drescher, Oleg Kornilov, Tobias Witting +6
Refraction is a well-known optical phenomenon that alters the direction of light waves propagating through matter. Microscopes, lenses and prisms based on refraction are indispensa…
