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…
Terahertz imaging with sub-wavelength resolution by femtosecond laser filament in air
Jiayu Zhao, Wei Chu, Lanjun Guo +4
Terahertz (THz) imaging provides cutting edge technique in biology, medical sciences and non-destructive evaluation. However, due to the long wavelength of the THz wave, the obtain…
Terahertz Wave Guiding by Femtosecond Laser Filament in Air
Jiayu Zhao, Yizhu Zhang, Zhi Wang +5
Femtosecond laser filament generates strong terahertz (THz) pulse in air. In this paper, THz pulse waveform generated by femtosecond laser filament has been experimentally investig…
Tunable frequency reference by optical pumping-assisted intracavity V-type electromagnetically induced transparency
Kang Ying, Yueping Niu, Dijun Chen +3
A tunable high resolution frequency reference is constructed using the narrowed cavity-linewidth by the optical pumping-assisted V-type electromagnetically induced transparency (EI…
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…
Initial carrier-envelope phase of few-cycle pulses determined by THz emission from air plasma
Rongjie Xu, Ya Bai, Liwei Song +3
The evolution of THz waveform generated in air plasma provides a sensitive probe to the variation of the carrier envelope phase (CEP) of propagating intense few-cycle pulses. Our e…
Observation of Multi-Electromagnetically Induced Transparency in V-type Rubidium atoms
Kang Ying, Yueping Niu, Yihong Qi +4
A detailed experimental investigation and theoretical analysis have been made in the V-type 85Rb atomic medium. Seven induced transparency windows, including a central double-peak-…
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…
Single-shot Sub-Rayleigh Imaging with Sparse Detection
Wenlin Gong, Shensheng Han
For conventional imaging, the imaging resolution limit is given by the Rayleigh criterion. Exploiting the prior knowledge of imaging object's sparsity and fixed optical system, ima…
