Symmetry-Breaking Electron Dynamics Enable Ultrabroadband Optical-Field Sampling via Second-Harmonic Generation
Wenqi Tang, Ahai Chen, Michael Klaiber +4
Optical-field sampling using second-harmonic generation (SHG) from strong-field ionization enables ultrabroadband terahertz detection, but the microscopic origin of the SHG signal…

Role of quantum dynamics in coherent and incoherent radiation during tunneling ionization
Michael Klaiber, Karen Z. Hatsagortsyan, Christoph H. Keitel
Radiation during strong-field tunneling ionization is investigated. The spontaneous as well as the coherent components of the radiation are calculated describing the ionization dyn…

Low-energy photoelectron structures for arbitrary ellipticity of a strong laser field
Q. Z. Lv, M. Klaiber, P. -L. He +2
Previous attoclock experiments measuring the photoelectron momentum distribution (PMD) via strong-field ionization in an elliptically polarized laser field have shown anomalously l…
