Probing Electronic Motion and Core Potential by Coulomb-reshaped Terahertz Radiation
Ziyang Gan, Kaixuan Zhang, Yuan Gao +5
The nature of electronic motion and structural information of atoms and molecules is encoded into strong-field induced radiations ranging from terahertz (THz) to extreme ultraviole…
Coulomb potential determining terahertz polarization in two-color laser field
Yuan Gao, Yizhu Zhang, Kaixuan Zhang +3
The orientation and ellipticity of terahertz (THz) polarization generated by two-color strong field not only cast light on underlying mechanisms of laser-matter interaction, but al…
Few-photon single ionization of cold rubidium in the over-the-barrier regime
Huanyu Ma, Xincheng Wang, Linxuan Zhang +9
Photoionization of the rubidium (Rb) atoms cooled in a magneto-optical trap, characterized by the coexistence of the ground 5 and the excited 5 states, is investi…
Intensity-surged and Bandwidth-extended Terahertz Radiation in Two-foci Cascading Plasmas
Yizhu Zhang, Zhi-Hong Jiao, Tao He +7
The two-color strong-field mixing in gas medium is a widely-used approach to generate bright broadband terahertz (THz) radiation. Here, we present a new and counterintuitive method…
Rydberg blockade in an ultracold strontium gas revealed by two-photon excitation dynamics
Chang Qiao, Can-Zhu Tan, Julia Siegl +5
We demonstrate the interaction-induced blockade effect in an ultracold Sr gas via studying the time dynamics of a two-photon excitation to the triplet Rydberg series $5\math…
Observation of photon recoil effects in single-beam absorption spectroscopy with an ultracold strontium gas
Fachao Hu, Canzhu Tan, Yuhai Jiang +2
We report on observing photon recoil effects in the absorption of a single monochromatic light at 689~nm through an ultracold Sr gas, where the recoil frequency is comparabl…
Ellipticity-dependent sequential over-barrier ionization of cold rubidium
Junyang Yuan, Shiwei Liu, Xincheng Wang +10
We perform high-resolution measurements of momentum distribution on Rb recoil ions up to charge state , where laser-cooled rubidium atoms are ionized by femtosecond ell…
Momentum spectroscopy for multiple ionization of cold rubidium in the elliptically polarized laser field
Junyang Yuan, Yixuan Ma, Renyuan Li +8
Employing recent developed magneto-optical trap recoil ion momentum spectroscopy (MOTRIMS) combining cold atom, strong laser pulse, and ultrafast technologies, we study momentum di…
Strong-field extreme-ultraviolet dressing of atomic double excitation
Christian Ott, Lennart Aufleger, Thomas Ding +21
We report on the experimental observation of strong-field dressing of an autoionizing two-electron state in helium with intense extreme-ultraviolet laser pulses from a free-electro…
Dual-Color Laser Induced Terahertz Generation in Strong Field Approximation
Kaixuan Zhang, Yizhu Zhang, Shuai Li +3
The mechanism of the terahertz (THz) wave generation (TWG) in dual-color fields is elucidated within the theoretical framework of single-atom based strong field approximation (SFA)…
Analyzing a single-laser repumping scheme for efficient loading of a strontium magneto-optical trap
Fachao Hu, Ingo Nosske, Luc Couturier +6
We demonstrate enhanced loading of strontium atoms into a magneto-optical trap using a repumping scheme from the metastable state via the doubly-excited state $5\mathrm{s}5\mathrm{…
Laser frequency stabilization using a commercial wavelength meter
Luc Couturier, Ingo Nosske, Fachao Hu +5
We present the characterization of a laser frequency stabilization scheme using a state-of-the-art wavelength meter based on solid Fizeau interferometers. For a frequency-doubled T…
Noisy pulses enhance temporal resolution in pump-probe spectroscopy
Kristina Meyer, Christian Ott, Philipp Raith +7
Time-resolved measurements of quantum dynamics are based on the availability of controlled events (e.g. pump and probe pulses) that are shorter in duration than the typical evoluti…
