Terahertz field induced near-cutoff even-order harmonics in femtosecond laser
Bing-Yu Li, Yizhu Zhang, Tian-Min Yan +1
High-order harmonic generation by femtosecond laser pulse in the presence of a moderately strong terahertz (THz) field is studied under the strong field approximation, showing a si…
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…
Terahertz Emisssion from Quantum Interference of Electron Trajectories
Yizhu Zhang, Kaixuan Zhang, Tian-Min Yan +1
The semiclassical electron trajectory, the so-called quantum orbits, is employed to explain the terahertz wave generation (TWG) in dual-color strong field, and the feasibility of t…
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…
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)…
Applicability of coupling strength estimation for linear chains of restricted access
He Feng, Tian-Min Yan, Y. H. Jiang
The characterization of an unknown quantum system requires the Hamiltonian identification. The full access to the system, however, is usually restricted, hindering the direct retri…
