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…
