High-energy, few-cycle light pulses tunable across the vacuum ultraviolet
José R. C. Andrade, Martin Kretschmar, Rostyslav Danylo +8
In the last few decades the development of ultrafast lasers has revolutionized our ability to gain insight into light-matter interactions. The appearance of few-cycle light sources…
Multiple-Photon Resonance Enabled Quantum Interference in Emission Spectroscopy of N_2^+
Xiang Zhang, Qi Lu, Yalei Zhu +13
Quantum interference occurs frequently in the interaction of laser radiation with materials, leading to a series of fascinating effects such as lasing without inversion, electromag…
Quantum erasing of laser emission in N
Rostyslav Danylo, Guillaume Lambert, Yi Liu +3
Cavity-free lasing of N induced by a femtosecond laser pulse at 800~nm is nearly totally suppressed by a delayed twin pump pulse. We explain this surprising effect within the…
Theory of femtosecond strong field ion excitation and subsequent lasing in N
Vladimir T. Tikhonchuk, Yi Liu, Rostyslav Danylo +2
Delayed cavity-free forward lasing at the wavelengths of 391 and 428 nm was observed in recent experiments in air or pure nitrogen pumped with an intense femtosecond laser pulse at…
Lasing without population inversion in air
André Mysyrowicz, Rostyslav Danylo, Pengji Ding +8
A cavity-free laser in the sky could lead to revolutionary improvements in optical remote sensing for atmospheric science. Abundant in air, nitrogen molecules are prime candidates…
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…
