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…
Low-threshold whispering-gallery-mode microlasers fabricated in a Nd: glass substrate by three-dimensional femtosecond laser micromachining
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…
