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…
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…
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…
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{…
