Lin K, Eckart S, Liang H, Hartung A, Jacob S, Ji Q, et al.
Science . 2024 Mar; 383(6690):1467-1470. PMID: 38547290
Similar to the optical diffraction of light passing through a material grating, the Kapitza-Dirac effect occurs when an electron is diffracted by a standing light wave. In its original description,...

Pan S, Zhang Z, Xu L, Zhang W, Lu P, Ji Q, et al.
Phys Rev Lett . 2023 Apr; 130(14):143203. PMID: 37084425
We demonstrate that dissociative ionization of H_{2} can be fully manipulated in an angle-time-resolved fashion, employing a polarization-skewed (PS) laser pulse in which the polarization vector rotates. The leading and...

Pan S, Zhang W, Li H, Lu C, Zhang W, Ji Q, et al.
Phys Rev Lett . 2021 Feb; 126(6):063201. PMID: 33635700
The dissociative above-threshold double ionization (ATDI) of H_{2} in strong laser fields involves the sequential releasing of two electrons at specific instants with the stretching of the molecular bond. By...

Lin K, Hu X, Pan S, Chen F, Ji Q, Zhang W, et al.
J Phys Chem Lett . 2020 Apr; 11(8):3129-3135. PMID: 32233496
We experimentally investigate the ultrafast photodissociation dynamics of the SO molecule induced by intense ultrashort laser pulses in a pump-probe scheme. Different three-body fragmentation pathways are discriminated using the time-dependent...

Ji Q, Pan S, He P, Wang J, Lu P, Li H, et al.
Phys Rev Lett . 2019 Dec; 123(23):233202. PMID: 31868470
We experimentally observe the bond stretching time of one-photon and net-two-photon dissociation pathways of singly ionized H_{2} molecules driven by a polarization-skewed femtosecond laser pulse. By measuring the angular distributions...

Zhang W, Gong X, Li H, Lu P, Sun F, Ji Q, et al.
Nat Commun . 2019 Feb; 10(1):757. PMID: 30765696
Atoms and molecules exposed to strong laser fields can be excited to the Rydberg states with very high principal quantum numbers and large orbitals. It allows acceleration of neutral particles,...

Lin K, Tutunnikov I, Qiang J, Ma J, Song Q, Ji Q, et al.
Nat Commun . 2018 Dec; 9(1):5134. PMID: 30510201
Orientation and alignment of molecules by ultrashort laser pulses is crucial for a variety of applications and has long been of interest in physics and chemistry, with the special emphasis...

Song Q, Li Z, Li H, Lu P, Gong X, Ji Q, et al.
Opt Express . 2018 Mar; 25(3):2221-2227. PMID: 29519070
The dissociative ionization of CO in orthogonally polarized femtosecond laser pulses are studied in a pump-probe scheme. The ionization of CO by the pump pulse and the dissociation of the...

Lu P, Wang J, Li H, Lin K, Gong X, Song Q, et al.
Proc Natl Acad Sci U S A . 2018 Feb; 115(9):2049-2053. PMID: 29440495
Electrons bound to atoms or molecules can simultaneously absorb multiple photons via the above-threshold ionization featured with discrete peaks in the photoelectron spectrum on account of the quantized nature of...

Zhang W, Yu Z, Gong X, Wang J, Lu P, Li H, et al.
Phys Rev Lett . 2018 Jan; 119(25):253202. PMID: 29303298
We experimentally visualize the dissociative frustrated double ionization of hydrogen molecules by using few-cycle laser pulses in a pump-probe scheme, in which process the tunneling ionized electron is recaptured by...
