Fabrication of microfluidic channels with a circular cross section using spatiotemporally focused femtosecond laser pulses
TL;DR: It is demonstrated both theoretically and experimentally that the spatiotemporal focusing of femtosecond laser beam allows for the creation of a three-dimensionally symmetric spherical intensity distribution at the focal spot.

Wei Chu,G. Li,Hongqiang Xie,Jielei Ni,Jinping Yao,Bin Zeng,Haisu Zhang,Chenrui Jing,Huailiang Xu,Ya Cheng,Zhizhan Xu +10 more
TL;DR: In this paper, a self-induced narrow-band laser at 428 nm has a pulse duration of 2.6 ps with perfect linear polarization property, which opens new possibilities for remote detection in the atmosphere.

Wei Chu,Wei Chu,G. Li,Hongqiang Xie,Jielei Ni,Jinping Yao,Bin Zeng,Haisu Zhang,Chenrui Jing,Huailiang Xu,Ya Cheng,Zhizhan Xu +11 more
TL;DR: In this paper, a self-induced white light inside the filament covering the transition is then serving as the seed to be amplified, which opens new possibilities for remote detection in the atmosphere.

TL;DR: By measuring the intensities of 337-nm signal from nitrogen gas mixed with different concentrations of oxygen gas, it is found that oxygen molecules have a significant quenching effect on the nitrogen laser signal.
