Enhanced Population on Ionic Excited States by Synchronized Ionization and Multiphoton Resonance
Yewei Chen, Hongbin Lei, Quanjun Wang +12
We study population distributions and lasing actions of N_2^+ driven by femtosecond lasers with various wavelengths, and uncover an efficient ionic excitation mechanism induced by…
Role of rotational coherence in femtosecond-pulse-driven nitrogen ion lasing
Hongqiang Xie, Hongbin Lei, Guihua Li +7
We experimentally investigated the rotationally resolved polarization characteristics of N lasing at 391 and 428 nm using a pump-seed scheme. By varying the relative angle be…
Sub-cycle coherent control of ionic dynamics via transient ionization injection
Qian Zhang, Hongqiang Xie, Guihua Li +7
We investigate the interwoven dynamic evolutions of neutral nitrogen molecules together with nitrogen ions created through transient tunnel ionization in an intense laser field. By…
Signature of multi-channel interference in high-order harmonic generation from N2 driven by intense mid-infrared pulses
Guihua Li, Jinping Yao, Xinhua Xie +10
We investigate the multi-electron dynamics in high-order harmonic generation (HHG) from N2 molecules. Clear spectral minima are observed in the cutoff region at all three mid-infra…
Reconstruction of a Rotational Wavepacket of Inverted Molecular Ions in an Intense Femtosecond Laser Field
Haisu Zhang, Chenrui Jing, Jinping Yao +10
We report on generation of a rotational wavepacket in the ground vibronic state (v = 0) of excited electronic B2Σu+ state of N2+ in a femtosecond laser induced plasma spark. Decodi…
Alignment-dependent fluorescence emission induced by tunnel ionization of carbon dioxide from lower-lying orbitals
Jinping Yao, Guihua Li, Xinyan Jia +13
Study on ionization process of molecules in an intense infrared laser field is of paramount interest in strong-field physics and constitutes the foundation of imaging of molecular…
