Low-threshold efficient N lasing driven by sub-cycle soliton dynamics in a hollow waveguide
Tiandao Chen, Zhiyuan Huang, Jinyu Pan +12
The phenomenon of N lasing, observed in femtosecond-laser filamentation, attract considerable interests in recent several years, with great application potentials in fields…
Femtosecond dynamics of a polariton bosonic cascade at room temperature
Fei Chen, Hang Zhou, Hui Li +11
Whispering gallery modes in a microwire are characterized by a nearly equidistant energy spectrum. In the strong exciton-photon coupling regime, this system represents a bosonic ca…
Gain dynamics of a free-space nitrogen laser pumped by circularly polarized femtosecond laser pulses
Jinping Yao, Hongqiang Xie, Bin Zeng +9
We experimentally demonstrate ultrafast dynamic of generation of a strong 337-nm nitrogen laser by injecting an external seed pulse into a femtosecond laser filament pumped by a ci…
Impulsive rotational Raman scattering of N2 by a remote "air laser" in femtosecond laser filament
Jielei Ni, Wei Chu, Haisu Zhang +8
We report on experimental realization of impulsive rotational Raman scattering from neutral nitrogen molecules in a femtosecond laser filament using an intense self-induced white-l…
Second harmonic generation in a centrosymmetric gas medium with spatiotemporally focused intense femtosecond laser pulses
Guihua Li, Jielei Ni, Hongqiang Xie +9
We demonstrate unexpectedly strong second harmonic generation (SHG) in Argon gas by use of spatiotemporally focused (SF) femtosecond laser pulses. The resulting SHG by the SF schem…
Signature of superradiance from a nitrogen gas plasma channel produced by strong field ionization
Guihua Li, Chenrui Jing, Bin Zeng +8
Recently, Yao et al. demonstrated the creation of coherent emissions in nitrogen gas with two-color (800 nm + 400 nm) ultrafast laser pulses [New J. Phys. 15, 023046 (2013)]. Based…
Self-induced white-light seeding laser in a femtosecond laser filament
Wei Chu, Guihua Li, Hongqiang Xie +8
We report, for what we believe to be the first time, on the generation of remote self-seeding laser amplification by using only one 800 nm Ti:Sapphire femtosecond laser pulse. The…
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…

Jintian Lin, Yingxin Xu, Jiangxin Song +6
We report on fabrication of whispering-gallery-mode microlasers in a Nd:glass chip by femtosecond laser three-dimensional (3D) micromachining. Main fabrication procedures include t…
Remote creation of strong and coherent emissions in air with two-color ultrafast laser pulses

We experimentally demonstrate generation of strong narrow-bandwidth emissions with excellent coherent properties at ~391 nm and ~428 nm from molecular ions of nitrogen inside a fem…
Harmonic-seeded remote laser emissions in N2-Ar, N2-Xe and N2-Ne mixtures: a comparative study
Jielei Ni, Wei Chu, Haisu Zhang +9
We report on the investigation on harmonic-seeded remote laser emissions at 391 nm wavelength from strong-field ionized nitrogen molecules in three different gas mixtures, i.e., N2…
Attosecond-recollision-controlled selective fragmentation of polyatomic molecules
Xinhua Xie, Katharina Doblhoff-Dier, Stefan Roither +8
Control over various fragmentation reactions of a series of polyatomic molecules (acetylene, ethylene, 1,3-butadiene) by the optical waveform of intense few-cycle laser pulses is d…
