Incubation Induced Light Concentration Beyond the Diffraction Limit for High-Resolution Glass Printing
Haisu Zhang, Peng Wang, Wei Chu +5
In the past two decades, tremendous efforts have been exerted to understand and control the delivery of ultrashort laser pulses into various types of transparent materials ranging…
Chirp control of directional current in monolayer graphene by intense few-cycle laser
Erheng Wu, Qiang Zhan, Zhanshan Wang +2
The residual current density in monolayer graphene driven by an intense few-cycle chirped laser pulse is investigated via numerical solution of the time-dependent Schrödinger equat…
Aberration-free three dimensional micromachining in glass with spatiotemporally shaped femtosecond laser pulses
Peng Wang, Wei Chu, Wenbo Li +5
We observe that focusing a femtosecond laser beam simultaneously chirped in time and space domains in glass can efficiently suppress the optical aberration caused by the refractive…
Harmonic-seeded resonant Raman amplification in strong-field ionized nitrogen molecules
Jinping Yao, Wei Chu, Chuanshan Tian +3
Generation of free-space laser-like emissions of high spatiotemporal coherence and narrow bandwidth in atmosphere opens promising opportunities for remote spectroscopic sensing. He…
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…
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…
