Rotational, Vibrational, and Electronic Modulations in N_{2}^{+} Lasing at 391 nm: Evidence of Coherent B^{2}Σ_{u}^{+}-X^{2}Σ_{g}^{+}-A^{2}Π_{u} Coupling.

TL;DR: By solving the time-dependent Schrödinger equation, the oscillations in the three different frequency ranges are reproduced and it is shown that the coherent population transfer among the three electronic states of N_{2}^{+} creates the population inversion between the B^{2}Σ_{u} and X-X-X states.
Journal ArticleDOI

Journal ArticleDOI
Stand-off fabrication of irregularly shaped, multi-functional hydrophobic and antireflective metal surfaces using femtosecond laser filaments in air
TL;DR: In this paper, the authors demonstrate an approach for rapid, standoff fabrication of multi-functional surfaces with super-hydrophobic and antireflective properties on irregularly-shaped samples, by texturing them with femtosecond laser filaments in air, followed by chemical fluorination treatment.
Journal ArticleDOI
Optimization of N 2 + lasing through population depletion in the X 2 Σ g + state using elliptically modulated ultrashort intense laser fields
Yao Fu,Erik Lötstedt,Helong Li,Siqi Wang,Danwen Yao,Toshiaki Ando,Atsushi Iwasaki,Farhad H. M. Faisal,Kaoru Yamanouchi,Huailiang Xu,Huailiang Xu,Huailiang Xu +11 more
TL;DR: In this paper, the authors generate air lasing by elliptically-modulated intense femtosecond laser pulses and show that the lasing intensities of N${}_{2}$${}^{+}$ at 391 and 428 nm can be manipulated by adjusting the temporal separation between the two polarization components in the elliptically modulated laser pulse and their relative amplitudes.
