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…
A low-energy compact Shanghai-Wuhan electron beam ion trap for extraction of highly charged ions
Shiyong Liang, Qifeng Lu, Xincheng Wang +16
A low-energy, compact and superconducting electron beam ion trap (the Shanghai-Wuhan EBIT or SW-EBIT) for extraction of highly charged ions is presented. The magnetic field in the…
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)…
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…
