On the Nonlinear Excitation of Phononic Frequency Combs in Molecules
Hongbin Lei, Qian Zhang, Hongqiang Xie +6
The mechanical analog of optical frequency combs, phononic frequency combs (PFCs), has recently been demonstrated in mechanical resonators via nonlinear coupling among multiple pho…
Electronic-vibrational dynamics and coherence in x-ray transient absorption of N2+ induced by strong-field ionization
Jing Zhao, Guangru Bai, Qian Zhang +8
Attosecond transient absorption spectroscopy (ATAS) is becoming an indispensable and powerful tool in the emerging field of attochemistry, while the interpretation of measurements…
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…
