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…
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…
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…
Recoil-ion momentum spectroscopy of photoionization of cold rubidium atoms in a strong laser field
Renyuan Li, Junyang Yuan, Xinya Hou +11
We study photoionization of cold rubidium atoms in a strong infrared laser field using a magneto-optical trap (MOT) recoil ion momentum spectrometer. Three types of cold rubidium t…
Terahertz generation in dual-color laser: continuum electron in strong-field single-atom ionization
Kaixuan Zhang, Yizhu Zhang, T. -M. Yan +1
The terahertz (THz) generation in a dual-color field was investigated experimentally by precisely controlling the relative time delay and polarization of dual-color lasers,…
