Interferometric characterization of pulse front tilt of spatiotemporally focused femtosecond laser pulses for three-dimensional micromachining application
Zhaohui Wang, Fei He, Jielei Ni +6
We report on an experimental measurement of the pulse front tilt (PFT) of spatiotemporally focused femtosecond laser pulses in the focal plane in both air and bulk transparent mate…
Gain dynamics of a free-space nitrogen laser pumped by circularly polarized femtosecond laser pulses
Jinping Yao, Hongqiang Xie, Bin Zeng +9
We experimentally demonstrate ultrafast dynamic of generation of a strong 337-nm nitrogen laser by injecting an external seed pulse into a femtosecond laser filament pumped by a ci…
Impulsive rotational Raman scattering of N2 by a remote "air laser" in femtosecond laser filament
Jielei Ni, Wei Chu, Haisu Zhang +8
We report on experimental realization of impulsive rotational Raman scattering from neutral nitrogen molecules in a femtosecond laser filament using an intense self-induced white-l…
Real-time observation of dynamics in rotational molecular wave packets by use of "air laser" spectroscopy
Bin Zeng, Wei Chu, Guihua Li +6
Molecular rotational spectroscopy based on strong-field-ionization-induced nitrogen laser is employed to investigate the time evolution of the rotational wave packet composed by a…
