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…
