Observation of Fundamental Thermal Noise in Optical Fibers down to Infrasonic Frequencies
Jing Dong, Junchao Huang, Tang Li +1
The intrinsic thermal noise in optical fibers is the ultimate limit of fiber-based systems. However, at infrasonic frequencies, the spectral behavior of the intrinsic thermal noise…
Multispectral imaging using a single bucket detector
Liheng Bian, Jinli Suo, Guohai Situ +3
Current multispectral imagers suffer from low photon efficiency and limited spectrum range. These limitations are partially due to the technological limitations from array sensors…
Generation of elliptically polarized nitrogen-ion laser fields using two-color femtosecond laser pulses
Ziting Li, Bin Zeng, Wei Chu +6
We experimentally investigate generation of molecular nitrogen-ion lasers with two femtosecond laser pulses at different wavelengths. The first pulse serves as the pump which ioniz…
Time-resolved shadowgraphs of transient plasma induced by spatiotemporally focused femtosecond laser pulses in fused silica glass
Zhaohui Wang, Bin Zeng, Guihua Li +7
We report on experimental observations of formation and evolution of transient plasma produced in fused silica glass with spatiotemporally focused (STF) femtosecond laser pulses us…
Three-dimensional array foci of generalized Fibonacci photon sieves
Junyong Zhang, Jie Ke, Jianqiang Zhu +1
We present a new kind of photon sieves on the basis of the generalized Fibonacci sequences. The required numbers and locations of axial foci can be designed by generalized Fibonacc…
Fabrication of a microresonator-fiber assembly maintaining a high-quality factor by CO2 laser welding
Zhiwei Fang, Jintian Lin, Min Wang +4
We demonstrate fabrication of a microtoroid resonator of a high-quality (high-Q) factor using femtosecond laser three-dimensional (3D) micromachining. A fiber taper is reliably ass…
Direct observation of laser guided corona discharges
Tie-Jun Wang, Yingxia Wei, Yaoxiang Liu +10
Laser based lightning control holds a promising way to solve the problem of the long standing disaster of lightning strikes. But it is a challenging project due to insufficient und…
Generalized Fibonacci zone plates
Jie Ke, Junyong Zhang, Jianqiang Zhu
We propose a family of zone plates which are produced by the generalized Fibonacci sequences and their axial focusing properties are analyzed in detail. Compared with traditional F…
Formation of in-volume nanogratings with sub-100 nm periods in glass by femtosecond laser irradiation
Yang Liao, Wangjun Pan, Yun Cui +4
We present direct experimental observation of the morphological evolution during the formation of nanogratings with sub-100-nm periods with the increasing number of pulses. Theoret…
Spectral Camera based on Ghost Imaging via Sparsity Constraints
Zhentao Liu, Shiyu Tan, Jianrong Wu +3
The image information acquisition ability of a conventional camera is usually much lower than the Shannon Limit since it does not make use of the correlation between pixels of imag…
Population Redistribution among Multiple Electronic States of Molecular Nitrogen Ions in Strong Laser Fields
Jinping Yao, Shicheng Jiang, Wei Chu +11
We carry out a combined theoretical and experimental investigation on the population distributions in the ground and excited states of tunnel ionized N2 molecules at various driver…
Spatiotemporal focusing does not always improve axial intensity localization
Ya Cheng, Hongqiang Xie, Zhaohui Wang +6
We report on an experimental comparison on critical intensities of nonlinear self-focusing in air with conventional focusing and spatiotemporal focusing schemes. Our results show t…
Giant Two-Photon Absorption in Monolayer MoS2
Yuanxin Li, Ningning Dong, Saifeng Zhang +5
Strong two-photon absorption (TPA) in monolayer MoS2 is demonstrated in contrast to saturable absorption (SA) in multilayer MoS2 under the excitation of femtosecond laser pulses in…
Direct Observationof DegenerateTwo-Photon Absorption and Its Saturation in WS2 and MoS2 Monolayer and Few-Layer Films
Saifeng Zhang, Ningning Dong, Niall McEvoy +10
The optical nonlinearity of WS2, MoS2 monolayer and few-layer films was investigated using the Z-scan technique with femtosecond pulses from the visible to the near infrared. The d…

Ningning Dong, Yuanxin Li, Yanyan Feng +6
Nonlinear optical property of transition metal dichalcogenide (TMDC) nanosheet dispersions, including MoS2, MoSe2, WS2, and WSe2, was performed by using Z-scan technique with ns pu…
Joint time and frequency dissemination network over delay-stabilized fiber optic links
Wei Chen, Qin Liu, Nan Cheng +4
A precise fiber-based time and frequency dissemination scheme for multiple users with a tree-like branching topology is proposed. Through this scheme, ultra-stable signals can be e…
