Efficient cascaded wavelength conversion under two-peak Stark-chirped rapid adiabatic passage via grating structures
Handa Zhang, Xiang Zhang, Ting Wan +4
In this paper, we demonstrate a domain inversion crystal structure to study the cascaded three-wave mixing process in a two peak Stark-chirped rapid adiabatic passage. We have achi…

Coherent control of superradiance from nitrogen ions pumped with femtosecond pulses
An Zhang, Qingqing Liang, Mingwei Lei +8
Singly ionized nitrogen molecules in ambient air pumped by near-infrared femtosecond laser give rise to superradiant emission. Here we demonstrate coherent control of this superrad…

Backward lasing of singly ionized nitrogen ions pumped by femtosecond laser pulses
Xiang Zhang, Rostyslav Danylo, Zhengquan Fan +6
We report on the observation of backward lasing at 391.4 nm of nitrogen ions pumped by linearly polarized intense femtosecond pulses at 800 nm. The strongly enhanced spectral inten…
